This Halloween, in my Engineering Design and Society class, they hosted a challenge to create the best 3D printable jack-o-lantern. These were the given rules:

1. Must be an original creation of yours using Onshape for solid modeling
2. Must be a student in EGN2020C during Fall 2022 to enter
3. Submissions should be a one-page PDF, uploaded into Canvas, that includes the following:
4. Your creation must be able to fit a battery powered tea light into the body and show some sort of light through it. The nominal dimensions of the circular battery powered tea light are: 3.8 cm in diameter, and 3.4 cm tall
5. Estimated print time of your Jack-O’-Lantern, when brought into Cura at standard quality should be 8 hours or less

Example Projects:

We were required to use OnShape, which I had only learned this semester, but with my previous experience in Fusion360, it wasn’t difficult to learn. So I sat down for an evening and spend close to 4 hours designing this:

Wall-E Pumpkin

I don’t really know what inspired me to choose this pumpkin design, but once I started working on it, I fell in love. I put an excessive amount of effort into this project, and ended up winning first place.

They printed him for me, and provided the lights so I could light him up in my dorm for halloween.

Conclusion

In the end, the project was fun and gave me a lot more experience with OnShape, and I won a contest. I think its safe to say that I’m pretty efficient now with OnShape, and I’ve shown myself that I can adapt to new and different CAD softwares.
