Golf counter

A 'Jenny Cash' golf counter
- counts up to 11, making it a 2-digit counter
- noticeable click sound
It is very simple, both in design and in mechanics - it should last for long.

It's fully ABS printable, with a 0.4mm nozzle and 0.2mm layer height, including the spring. Support is required. Additionally needed parts:
- 2 screws M2x4 flat-head/sunken head (can be self-cutting)
- one short rubber band

Building: Start upside down, and put in the wheel first. The rubber band shall have an initial tension to always bring back the lever. Hook it on the left side, go over the bar on the left side of the lever, twist it, go over the lever, twist it again before going over the right bar and hook it on the right side. Put on the lid and lock it with the screws.

You could print the numbers with a different color, either with a dual-extruder setup or simply by switching the filament.
You could print the spring (and everything) in PETG. PLA can be used for everything but the spring.
