3D Printed Cartoon Ladybird

 

Challenge: For junior student to create an original insect, from scratch, using Tinkercad

Background: As regular visitors to this site will know we have one of our big school events incoming - our Pet Day for 2026.  When this takes place at the start of term four we have some class displays - one of which is a 'tin-can design' however with this design we wanted to showcase of the students creativity.  In this case our students have used their design skills in Tinkercad to create an insect that goes with the design.

We had a range of designs based on the students understanding of insects (which we had also been covering with our literacy work specifically our information report writing).  

 In this instance the student wanted to place the emphasis on the comedic value of the design making it cartoon like with its design.   The legs for the animal are in theory underneath and the wings are not separated as such.    Finally if you see the original design that was shown above the student was able to colour match the design, when the printing was completed the base colour was blue as shown, ideally the student would have had the option of a red or black base - or even a better solution would have been for the ability of the H2D Machine to print with a combination of two colours.     This has been demonstrated previously with our Warriors Coaster or last years Christmas decoration with the colours of Father Christmas.    One option that was not completed but this would have made an exceptional AR/VR projection object with a significant base and strong image.

Resourced used to create this print: iPad, Tinkercad App, Bambu H2D, Bambu PLA.

Level of Difficulty: Medium - as with the rest of the designs in this creation challenge the students were able to use their skills to create insects with a significant recognition factor.    

Size: The print measures 70mm across the front of the design and is 80mm long.   The design is 30mm high.

Cost/Price: The unit uses 30g of PLA filament to complete the print.  This has a price point of $0.58

Timeframe: This print took forty five minutes to complete.  This included a six minute timeframe for the printer to warm up and prepare for printing.

What we would do differently/Next Steps for the students: As noted there are a couple of design features that could be developed for the purpose of making it more realistic - the legs if they were added to the design would cause it to be somewhat unbalanced.     At this stage the size of the design is another slight issue - at 80mm and 90mm this is significantly bigger than its real-life version.

3D Customised Art Insects

Challenge: For an art design project/sculpture project created by the students to create and 3D design an insect that would work in conjunction with the art display.

Background: Using an Ultimaker 2+ as a printing tool, using Tinkercad as a design tool the students first sketched a diagram of an insect that was related to a plant that they were making that was constructed from wire - for instance a dragonfly with a cactus.    The students in the classroom were confident with using the 3D Printer having completed the introductory tasks that are listed on this blog.   The insects were designed by the ten and eleven year old students using the basic interface design and additional tools.    Students were concentrating on producing a print that was to scale so the print time for all of the insects or animals described here did not exceed twenty minutes and some of the smaller ones were under ten minutes.    

The students brief was to use the 3D Printer to design the insect/animal and additional features of the insects would be added once the creations had been spray painted.    Some of the smaller aspects of the insects are going to be added using additional media, such as wire for the antenna.

Level of Difficulty: Medium there are a variety of designs and creations in this sequence all of which have slightly different aspects.   These designs were all created by students who have used Tinkercad before and were confident in their abilities.   The final design of the plants themselves (such as the cactus shown on the left) is still to be completed so the size o the plants may be altered.   

Size: All of the prints were as close to the possible of the size of the actual insect - so they ranged from a few centimetres to the largest in this sequence which was the dragonfly.   This was 10cm long.  Some of the smaller designs, such as the Ladybugs shown on the left were only two or three centimetres across.

Timeframe: These prints did not take the typical length of time that are listed on this blog, this is primarily because of the scale of them.   By far the longest in the set was the dragonfly which came in at fifty minutes, as mentioned the smaller ones in the series were under ten each.

What we would do differently/Next Steps for the students: Using spray paint to decorate a number of the insects will be key to finishing their details and design.    Once a base coat has been applied additional details can be added to finish the designs.  The students also have been challenged to produce the insects to scale to complete the art design so there is potential to adjust some of the prints - given the length of time for each one and the PLA involved this is not a particularly major deal.
