Challenge: To repair a broken school trophy authentically with the 3D Printer for a presentation award.
Background: We've had two previous attempts at this project. The first attempt in August was from a virtual perspective when we didn't complete a design rather we took the first steps towards designing a solution.
In the second version, also published in August we looked at a further refinement of the design where we made an attempt to create something realistic.
The audience for this project was important - although we had a number of students start the project we were ultimately looking for a single print but one that could be mounted on the trophy, which is currently over thirty years old. It is due to be presented at our school prize giving at the end of this year. Despite appearances the trophy is essentially plastic. We have spent time looking at trying to create various Netball themed trophy toppers and have reached the conclusion that using a smaller trophy would likely give the best results. The two final designs are featured in this print.
This is the first in its final test phase. It has been created using the
Tinkercad template trophy design. To support it at the base a wedge has been developed that matches the base of the design. While it has been printed in pink its final design will be spray painted metallic and we will look at increasing the density of the print, which is currently based on the default.
The design was completed in under ten minutes by two students working together to complete the project. They did not require any teacher input.
Resources to complete this print: iPad, School Trophy (for dimensions), Tinkercad App, Tinkercad, Bambu P1S Printer, Bambu PLA (regular Cotton Candy).
Size: The print can be measured in two distinct parts. The wedge at the base is
80mm across 30mm long on the sides and 40mm wide at the back. It has a height of
20mm. The trophy itself is
70mm high and 80mm wide including the handles. This size is dictated by the desire to have the trophy sitting 'flush' on the top of the trophy base.
Cost/Price: This print uses 30g of PLA to complete the print, which includes two trees either side of the design to hold the handle in place. Based on this use of PLA the project has a price point of $0.60c.
Once the design was completed and the likely price was determined we also experimented with projecting the design onto the base as shown above top left. This gave us a clear idea of what the design would look like, as it was shown left with the physical print put in place and then placed in position on the trophy base.
Also of note at this point - we discovered that while this is a Netball trophy the ball in the top right hand front of the design, which is the actual original design for the trophy is a basketball!
Timeframe: To complete this print the printer was operating for one hour and eight minutes, including a six minute warm up time.
What we would do differently/Next steps for the students: In this instance the students want to check with the school to ensure that the trophy meets expectations. Once this has been sprayed metallic we should have two clear choices that will be available and then we will look at gluing the new top into place. We also will have the advantage of having the original design so we will be able to reprint it as required if there was to be any additional damage or issues with the trophy.
