It took me a few days to figure out what I should make, since there was a lot of choices available. What gave me a rough idea of what to make was this image that the teacher showed as an example(might be different, since i took this image off the internet):
After that, I thought to myself: "What if I made it such that you could move something in this model, but never be able to take it out no matter how you try?" Then I started drawing a simple idea in autocad
I then started making a model in fusion360.
So firstly, I made a box. Then I shelled it with 2mm wall thickness. Following that, I made a hole on 4 sides, each a different shape. Afterwards, I extruded the shape matching the holes. Lastly, I extruded an extension at the back and extruded a smaller cube in the middle to prevent it from being taken out from either side.
When I sliced the model, the printing time was 30mins with no support, so I scaled it in the Cura app to 75% of the original size, which reduced the time taken to 17mins.
- settings used:
as seen, the print is very small, and there was a bit of a failed print at the lower part of the extruded shapes on all 4 sides.
Here's how the file looks like (with download link at image below!)
