Flat-pack tiny coin block kit

For a video on how this was made (using FreeCAD and OpenSCAD), head [here]( youtu.be/omO25HhroCA)

I made this a few years back as a quick-print gift that I could make a bunch of and give away.

It's a tiny (12mm!) coin block with a separate coin- hitting the box from underneath with your finger lets you make the coin go up and down.

The end result was a bit too hard to put together to be as much fun as it might have been, but once it's together it's a fun little toy.
