I use it mainly for keeping track of HP/Mana in DnD, but it can count anything.
This is a copy of my remix of Nissenko's project from thingiverse.com.
I've redesigned inner rod to be separated from the caps. With addition of double-sided cap variant you can create your own combination of counters.
Print settings:
- nozzle size: 0.4
- layer height: 0.16 or 0.12 (for better quality)
- wall line count: 2-3 for more rigid shape
- infill: 20-30% should be sufficient
Post-Printing:
You just need to put rings on the rod and secure it with screwing caps on both sides. I advice securing caps by glueing them to the inner rod.
