Coin Pusher machine

This is a mini coin pusher machine.

It is design to play with 1 euro cents and 2 euro cents coins but you can use any coin with similar dimensions (15-25mm diameter and 1.7 - 2mm height).

I've built it around what I had lying around (especially a NEMA 17 stepper Motor, a stepper driver salvaged from a 3d printer and a ESP8266). These might not have been the best choices, but I wanted to stick with what I had on hand.

##BOM
- 12 M3 X 30mm screws
- 4 M3 X 10 mm screws
- 4 M3 X 20mm screws
- NEMA 17 stepper motor
- Stepper driver (pololu or equivalent, the application is really simple, anything capable of making a stepper driver make 360° turn with decent torque is sufficient)
- ESP8266 or any micro controller you are used to (Arduino)
- Power supply around 12V - 1A. I used a 15V .4A from a broken hair clipper. Not ideal but it works.
- All the printed parts

##Printing
- Dozer might need support for the s
