A storage box for all the tiny Cornelsen Einstern paper money and maths cards. 20cm by 20cm with a lid on top.

I created the box using https://bento3d.design.

The lid was created from scratch using Fusion 360.

There's a cutout to put the clock on top as well.

The name was added in the slicer afterwards.

The three longer pieces won't fit. I'll add another box for these later if possible on my bedsize.
