first attempt: the square one
This is the fastest model I made. It’s just two squares with a boolean operation.
then, the cylinder
I tried doing something with a few cylinders and some boolean operation. I also applied a beveling to smooth the corners.
I added a space of half a millimeter between the lid and the box.
It looks quite good. I think the space could be a little smaller for the lid to better hold.
making the lid a little bit bigger
Now it is a bit too large.
