This model is remixed from the original Maker Wallet designed by @flowalistik on Printables. It was then revamped by Marshal(on printables) who unfortunately removed the cash compartment. This was then added back by user Floptical(also on printable). All of the links should be listed somewhere, I'm not sure. I combined the revamped version and the files for the cash compartment.

Materials:

Filament about 30g (any is fine, although you may want abs/asa if it falls out a lot)

Assembly:
1. Place the pusher on to the body, it has a cylinder sticking out, place the pusher onto that.

2. Slide the middle into the body, there is a space in the walls of the body to make it slide in.

3. Connect the insert on the cover with the pusher.

4. Depending on how you connected the cover with the pusher, you may have to slide the cover to the side than back in.
