3D Printed Box

Learning Challenge - We are looking at Engineering currently at school.  As part of our unit we are looking at ways to challenge the students thinking with problem challenges.  The teacher wanted the students to focus on the hinge and the lid of the box.  To inspire the students the task was to design the reward box for students for the money offered during work in class as an incentive.
Background: The student responsible for the design and creation of this project had background working on various other projects using 3D Printers that have been detailed on this site.   Of note the teacher concerned had the project designed not with Tinkercad but with another program - in this case 123D Design.  In his opinion the program is superior to Tinkercad and should be used to allow student design.
Task: Design a box including a lid and hinge and 3D Print.  Box needs to be stable with a working lid.
Level of Difficulty: High. The box featuring the lid required working and movable parts - while the print was successful had the parts not worked a significant reprint and reworking would have been required.  The hinge was potentially difficult.
Issues: The print was successful on the first attempt. There was limited imperfection on the base of one corner but this was minor and unrelated to the design of the box.
Timeframe: Once again a 'fastprint' setting was used as it was a prototype.  This included a fourteen hour print for the box and an eight hour print for the plate that functioned as the lid.  The eight hours for the lid included the pin for the hinge.
Size: 18cm in length with a depth of 10cm and a width of 10cm.   Other parts relative.
Process: As noted the design was created by a student who used not Tinkercad but 123D Design.  As with other material on this site the Ultimaker 2 (regular) was used.

3D Printed Robotic Car

The original kit that inspired the task

3DPrintCar2016 - Kizoa Video Editor - Movie Maker

This project involved the teacher creating his own version of this car. It was inspired by an original Arduino Kitset. The kitset (completed) could be ordered online in its entirety - however the task was created to create one from scratch and 3D Print it.  The exception was the car components.  These were ordered online from a New Zealand supplier for a price of $11.80.   The pieces were then printed in stages and put together to produce the final piece.

Learning Challenge: Utilizing the 3D Printer to produce a kitset car that would work to complement the motor part of the kitset (see below).   The parts needed to ensure that the motor would work.
Level of Difficulty: As a prototype the teacher wanted to complete the task first.  In addition to the regular parts of the car additional parts to house the additional components and features needed to be made and constructed.  This has been intended as a practise run before the students complete the task.
Issues: The axel space around the wheels was not clear enough which led to a restriction in the movement.  In future print runs this area of the car would need to be addressed to allow it to move freely.

The New Zealand kitset version

Timeframe: Fourteen hours for the base, twelve hours for the front bumpers and an additional twenty hours for the remaining parts of the car.  This car was printed on the 'fast/draft' setting as it was a prototype - there was concern that it would be robust enough to handle the task of the car running however this is not the case.
Size: Twenty five centimetres in length and fifteen centimetres across.
Moving Forward: The intention with this task is for the students to complete the task individually and produce their own version of this project.

3D Print School: Replacement Game Pieces

Replacement piece in cardboard (left)

Learning Challenge: To replace missing pieces of a game to ensure that the game is playable.  As part of the classroom resources there is a pack of 'wet lunchtime games'.  The purpose of these games is to ensure that the students can be occupied during times that the weather prevents them from going outside.  Some of the games have smaller game pieces that are plastic that overtime have been lost.

Some of the game pieces had been replaced by cardboard cut outs of various pieces (see right) - however the students when brainstorming ideas about using the 3D Printers in the classroom they felt that the could reproduce the pieces better and in more detail using the 3D Printers.

Tinkercad search of 'Cluedo'

Background: This task enabled the classroom of students to be involved in a straightforward task.  There were six items altogether that needed to be recreated, which meant that we had three to four students in each group.  In the first instance we looked at replacing the items with the original game pieces - these could be done relatively cheaply however we wanted to incorporate the technology.  We looked at Tinkercad to see if someone had already produced them - and couldn't find the existing regular items but did find a version of it.  However this didn't align to the existing cards that were produced with the games.   It meant as a consequence that the game couldn't have been played with the existing game cards.

Task: Students had to design the game pieces and 3D Print them to replace the following items: rope, lead pipe, knife, spanner/wrench, candlestick or revolver. These would be the size that would allow them to be used as replacement parts in the game.

Level of Difficulty: Some of the weapon items were straightforward - such as the lead pipe.  The more difficult items such as the revolver were extremely challenging for students to create the detail.  This group of students identified that Tinkercad had pre existing revolvers that they could have used however the intention was to replace with original student designs.

Some items to be improved...

Issues: Detail on the designs related to the size of the items - there were some items that required considerable detail and others did not.

Timeframe: The size of the six items to fit for their use in the game meant that under a regular print the print time was 70 minutes.

Size: Each of the items was of various size from 4-5cm with a width of between 1cm and 2cm. Process: designed on paper to start with, created in Tinkercad.  Converted to Cura and printed using Ultimaker 2.

Moving Forward: Replacement game pieces has potential to be a good introductory task for 3D Printing in the classroom.  It is a simple practical task (although it must be noted the difficulty of some of the items varied greatly) that would allow something to be used in the classroom and therefore could be particularly ongoing task.

3D Print School: Printed Golf Flag

Learning Challenge: To use the 3D Printers in conjunction with the EVO Robotics as part of the school technology program.  The task was for the students to design a Golf Flag as a target with the idea that the robot would be able to launch a golf ball into it.
Background: Auroa Primary School hosts its own technology program and in an attempt to integrate the 3D Printers in use in another area of the classroom program it was combined with a task involving robotics.  Students have technology every Friday from 9am until 2pm for half of the School year.  They have five week blocks at each of the four key areas (Sewing, Food Technology, Robotics and Woodwork).  Last year the 3D Printing Technology was a stand alone program that resulted in the 3D Printed Speakers.
Task: Students had to create (using Tinkercad) a 3D Design for a Golf Flag/hole that was suitable for a golf ball to be rolled into.
Level of Difficulty: Low - this design was the particular students first ever using Tinkercad and was completely independently with another student providing limited assistance.

Issues: The size of the target for the golf ball to enter was an estimation.   There are other designs in the series where the target is too narrow making the task extremely complex.  As a bonus this tee would be excellent for general practise with golf putting.
Timeframe: 12 hour print
Size: 15cm wide, depth of 15cm and a height of 20cm
Process: Template designed in Tinkercad.   Students then edited design (with another students assistance.  Converted to Cura and printed on the Schools Ultimaker 2 3D Printer.

3D Print School: Y3/4 Bookmarks

One of the challenges for 3D Printing is allowing younger students sometimes access to and use of the machines.   Our School has targeted this group of students with a Junior STEM program, with the intention of giving the students access to 3D Printing in the Classroom.  The initial design for this project, created by the School Principal, Heath Chittenden, was students creating a book mark suitable for reading.   Students were given a Tinkercad logon which they used to refine their design on the basis of circles - they picked up the process quickly.  Extension for the students came from a student who created a ring.

Learning Challenge: To design and create a 3D Printed Bookmark suitable for use with a book.  Students to use a basic design (featuring the circles) and then added their individual touches.
Background: Using the 3D Printers with students in the Junior School.  Junior School in New Zealand equates to students between the ages of 5 and 9 years old, although this class were 8 and 9 year old children.  Lessons took place for an hour once a week.
Task: Students had to design, manufacture and make a working bookmark.
Level of Difficulty: Low - a template was used for the basic design for the students.

Issues: student originally had some feet an antenna that while they added some detail to the creature tended to be flimsy and easily broke off or had to be removed after the final print.  As an added detail the filament used to print the bookmarks was glow-in-the-dark filament.
Timeframe: 3-4 hours on basic print settings.
Size: As seen from the shot 20cm in length and a depth of two to three centimetres

Process: Template designed in Tinkercad, shared with students.  Students then edited the design, and added additional features.   Converted to Cura and printed on the Schools Ultimaker 2 3D Printer.

Student Created Trophy for Sports

Students original Tinkercad Design

Learning Challenge: This student independently created and designed this project, having had previous experience during the Auroa Primary School Technology 3D Printing School program. They were a Hockey student who wanted to remember the season with a trophy.
Background: The student having had experience with the machines and the program wanted to gain additional credits towards the school rewards program and also recognise the (field) Hockey season which had been completed.
Task: The student generated the design in their own time using Tinkercad without teacher input.

Students design printing on the Ultimaker 2

Level of Difficulty: Moderate - the design required some modification (see below) however it was not significant and was completed on the initial print run successfully.
Issues: the original design came with a stick on the ground, sans the hockey ball, the ball was added to give stability to the design as the stick by itself was lacking in support.   The design of the ball was intended to stabilise design and not necessarily based around scale of an actual Hockey Ball.  The original Tinkercad design by the student featured two designs at the student wanted two copies.
Timeframe: The student came completed with the full design having done so in her own time.  Forty hours to print.
Size: Base 20cm, depth 15cm, height 25cm.  (approx.).
Process: Designed straight into Tinkercad.   Downloaded in the Cura, the Ultimaker 2 Free Software.  As per the rest of the material on this site it was created (printed using an Ultimaker 2)
