3D Printed Cart Holders - Bambu Labs

 

We are always looking for examples of resources that could potentially be made, created or designed for the classroom or students.

Recently one of our wonderful teachers was printing a set of card holders, while they were designed to hold the specific cards to a game they also could have a great potential in the classroom as a resource.

We have explained that we made the decision to change our printers to Bambu Labs/Bambu printers during 2025 replacing previous brands.    We are incredibly lucky to have three machines to run at our school.   Bambu Printers come with an extensive online data base of pre-made resources, pages and literally hundreds of designs about many topics.

In this instance these as standard card holders - they measure 90mm by 65mm and are 17mm high.   Crucially and this again demonstrates the powers of the machines the boxes have a width of 1nm and was produced without any support or waste plastic.

In a classroom environment it would be easily possible to personalise these boxes by including a name or a description on the outside of the box.    These boxes took five hours to print - however this included the printing of three boxes and three inserts.   This used  110g of PLA to complete the print and had a price point of $2.20c.

There are a number of students who play various card games here at school, and again the clear potential here is for this design to be used as a stepping point or an idea to encourage students with their own designs using part of this as a starting point.

Holiday Break: October 2026

For those of you who are unfamiliar with our location, we are located in rural New Zealand at the wonderful Auroa, South Taranaki.   We have great location, this photograph was taken today at lunchtime outside our school looking towards the maunga/mountain that dominates our landscape, Mount Taranaki.

Our students are currently on the second week of their two week break between terms three and four of 2026.  We will be back posting next week with our regular contributions.

In the meantime we are looking at a range of posts from last term that our students were working on. 

As we've mentioned in a post last week as such we don't have a massive seasonal celebration at the moment, and our friends in the USA obviously have a large volume of material themed around celebrations later this month.

We are printing a small selection of material primarily to encourage 'thinking' and design about it from students with this theme, including some of our Pumpkin AR/VR work from the end of term.

This design was located online and has a diameter of 50mm.   It is 30mm high.  It has used 22g of PLA to complete the print and has a price point of $0.45c.

While it would not suit a candle due to it being PLA printed it would potentially benefit from having an LED light inside of it.    Free .STL files such as this one are available in significant numbers and can be easily accessed for printing purposes.   We usually print a small number of such items where appropriate and ask students to consider or think about them.

3D Printing 2026: Lore Revision (Part One)

During the course of the year we've had a series of 'discussion' posts or focus challenges based around some thinking about the application of 3D Printing at our school and how it might be applied to other educational environment.

#1 You don't need more than one printer at your school to print your projects: (originally published in December 2025).   Evaluation: Not successful - we were attempting to complete all our prints on one machine this year however we have been switching between three machines depending on what has been available or what needed to be completed.   We had times when the Bambu H2D needed to have a nozzle replacement as a result of use, which meant we had to use of P1S to complete projects at that time.  Blog Tag to search for further information: Bambu H2D, Bambu P1S.

#2 All your 3D Print Projects don't need to end in a physical print. (originally published in January) Evaluation: Successful.   By using Tinkercad as a design tool with our iPads we have continued to follow a process to create and produce a digital outcome first and foremost before we make a physical print.  There are significant examples of this process and output on this blog for nearly every project that our students have completed and entire slideshows of summary work dedicated to this process.   Blog Tag to search for further information: AR/VR, Tinkercad AR/VR.

#3 Enhancing your projects by using non-standard PLA for different outputs. (originally published in January).   Evaluation: Successful.   We have used a range of filament this year again including a considerable amount of Bambu branded glow-in-the-dark and super glow-in-the-dark filaments.    Blog Tag to search for further information: glow-in-the-dark.

#4 Juniors can create! (originally published in January 2026) We wanted to challenge the notion that 3D Printing, CAD Design and creation is a senior school activity.   We have a classroom of Y4 students which is the core of nearly every print produced and showcased on this blog.   Evaluation: Successful. Blog Tag to search for further information: Anything that is not tagged Y7/8 is 'junior'.

This is part one of two.

3D Printed Ant: Standard Version

 

Challenge: To create an original and correct insect student (nine year old) designed 3D Print.

Background: As per the last few number of prints on this blog this is in preparation for our 2026 Pet Day.

As per the post from yesterday we experimented with using the P1P Bambu Printer and the Bambu H2D.   With the experience yesterday we printed on the Bambu H2D first and then followed up with P1S when the Bambu H2D didn't print the leg at the back.

As we suspected the print needs to be slowed down, by printing on the P1S we printed an identical design, an identical file but this was successful.   If we were using the Bambu H2D we would slow the process down.

Resources used to complete this print: iPad, Tinkercad App, Bambu P1P, Bambu Blue PLA.

Size: The print measures 55mm wide across at the front from the tip of each leg.   The print has a length of 70mm and the print is 55mm high.  The student (who is nine years old) deliberately introduced the legs and antenna to ensure that they survived the printing process and were not too weak, although it did leave them looking decidedly oversized and blocky.

Cost: To produce this print the project used 38g of regular PLA.   This gave the project a price point of $0.38c.

Timeframe: To complete this print the printer was running for one hour and ten minutes.   This is typical for designs in this run of creations with these dimensions.

What we would do differently/Next steps for the students: The ant when compared to others in the series does not have the facial definition that the others have.   The legs were increased in dimensions and size to ensure that they survived printed but now look somewhat comical and also are identical.   Finally the colour matching or the decorating, spraying etc of the print could be considered to enhance its presentation.   We still have a week of school before the Pet Day (which is in Term Four, the first week back after another week of holidays) and given the size of the print a reprint is a distinct possibility.

3D Printed Ant: Advanced Version

 

Challenge: Create a unique and detailed insect using Tinkercad to define and detail the features.

Background: Its been detailed on this blog for several weeks about the insect project which came from a focus on our 20206 Pet Day Art Display.

As part of the art display we've got a small 3D Print to go back and put on display with our art projects.   The challenge is based around shared literacy tasks - last term we researched, investigated and wrote about insects and analysed their characteristics and features.  This design was influenced by some of the earlier ants in the series that had the form and character correct but were lacking somewhat in some of the more detailed features.

When you view the face of the design you can see the student has opted for antenna, eyes and also the mouth has been based around viewing close up and magnification of various ants.   This student also went further making this a 'fire ant' and was able to adapt the colour palette on Tinkercad to do so.

There was a technical error that occurred with the printing of this design, one we are going to investigate further.  The student designed this as per our usual process - and one of the legs, at the back left, did not print successfully on the Bambu H2D - although it did on the P1S.    We believe based on a quick investigation that the speed of the H2D in this instance was too quick for the design, and the shaking and the movement of the printing process caused the fault in the process - this is the potentially the case as the smaller, cheaper machine was able to print the design successfully without any error.

The student who designed this print spent time to ensure the legs were shaped and had segmented detail on them.    There are grooves in the mouth of the ant and additional small details throughout the design.

Resources used to complete this print: iPad, Tinkercad App, Bambu H2D, Bambu Blue PLA

Size: The print at present is 80mm long, is 40mm from the base of the feet to the stop of the segments.   The biggest body segment is 30mm by 30mm and the middle is 20mm by 20mm.

Cost: The print uses 67g of PLA to complete the print which included rafting.   This gave the print a price point of forty one cents to complete.

Timeframe: To complete the print the Bambu H2D was running for one hour and eight minutes.  A switch to a Bambu P1S would not significantly alter the timeframe.

What we would do differently/Next steps for the students: It is our clear intention to print this on the slower, smaller printer as we believe the print will be successful (we could also slow down the H2D).  The intention was to print a fire ant with a red base obviously the PLA used was red although potentially we could have made a two coloured print using the dual nozzles of the machines.   The legs also at present have the same pose on both sides the student has the ability and the skill to pose these differently and produce a design that is reflective of a more natural post.   As noted as well the width of both the legs and the antenna reflect the students desire to create a robust print that would survive handling.

This entire project was undertaken and completed (independently) by a nine year old cohort two student.

Using Tinkercad as an AR/VR Tool

 

We've posted about our favourite app that our students use with their iPads to develop design skills using Tinkercad as a projection AR/VR tool.

In this example shown left we've taken a basic design.  As somewhat of an aside at our school due to our rural location we don't typically celebrate this event, although there are a wealth of designs that are available about this theme. 

In this example we had a short window of time available to students to complete a design and have some creative licence with it.   It was not intended as a 3D Print project although we would conceivable do so if the right circumstance was completed - we were looking as original projects developed by the students that would make a viable print.

This activity was completed by eight year olds working with their iPads independently.   The design of the pumpkin was located online, the students modified them by adding the lettering above and then located places around the school where they could project the pumpkin.   They deliberately choose to build the designs as large as possible and choose a location where the background had objects that would automatically size the objects, 

In the first instances the students used the school courts, swimming pool and buildings.   The instructions from the screenshot are from the Tinkercad app.   The students then repeated the process at a second location, which was on the courts.   The Netball Court/Basketball court and its fence was the sizing (as was the bus) which again allowed the student to show the size of the AR/VR that they had created.

The final part of the display process was to take the students images and then apply them through a AR/VR image filter.  In this case as we have done in the past we used Pic Collage to take the image and modify it.   You can see the contrast between the two images the image above and the same image with its enhanced result with a change and colour and emphasis on different parts of the photograph.

Obviously we could have looked to turn this final image (once edited and cleaned up) into a cart or a poster.    This is a process that we have completed using the Christmas/Festive filter which you can view by clicking on the link here.

3D Printed Insect - Generic Example

 

Challenge: To produce a unique and individual insect for display for the school Pet and Calf Day 2026.   You can view a highlight of last years event by clicking on the link here.

Background: This project has been detailed numerous times during the last few days and weeks - a small reminder that its school holidays in New Zealand and our students are going to be back in the classroom for Term Fur, the last quarter of the year for 2026 in a week and a half.

In case of the students designs we've had butterflies, stick insects and a range of bugs which we've detailed via this blog as students are printing one for display with our art pieces.   The students are also going to AR/VR their design into a couple of different locations around the school, one with the bug in its natural habitat and the second where the bug is going to be super sized, this is being completed by using the iPad and the TInkercad App.

This example shown left has all of the features that the students were looking to feature in their designs from the correct number of legs, located in the right position, the antenna, the head, thorax and abdomen.  As we have stated with this task the students have been able to access third party creations although we have made it clear that we expect that the students have personalised, modified or adapted these in a way that takes some of the design component and changes it.

Resources used to complete this print: iPad, Tinkercad App, Bambu H2D, Bambu Blue PLA

Size: The print is one of the smallest in the series.  It measures 40mm long and is 20mm wide.  The print currently stands 30mm to the head and the antenna are another 10mm higher.

Cost:   The print uses 8g of PLA to complete the print giving it a price point of $0.16c.

Timeframe: To complete this print on the Bambu H2D the print took forty minutes to complete which included the six minute warm up time (so the project print was just over half an hour) this was completed using the regulation default settings.

What we would do differently/Next steps for the students: The biggest thing would be for the students to modify this in a way that shows that they can manipulate an image or a design to put their own stamp more onto it.  One thing that has sprung to mind is that the bug could be produced, in some number and they could be included throughout the classroom and we could put up something up for someone who could find each of the designs.
