Super small wound/life tracker that can count 0-99 using two separate overlaying discs, with a spring to help make the numbers stay still. Fully printable using a 0,4mm nozzel. No screws, glue or grease required!

A downscale from my previous uploaded wound counter found here: 

This new version is only 27x33mm (among the smallest counters on the platform), skips the mechanical parts but keeps the plastic spring.
The plastic spring should be printed in PETG. I have also uploaded a spring free profile that is only printed in PLA!

Assembly instructions for both versions (spring free version simply ignores the spring instructions):

Take note that there are two different numbered rings for this! One clockwise and one counter-clockwise.

Take the front cover with the pin hole and place the clockwise numbered ring face down inside it, with one of the springs in the leftover slot like the image below

Take the counter-clockwise numbered ring and place on top of the first ring, but along the other side of the center pin slot. Place the second spring in the leftover slot like in the image below

Take the back cover and push in place against a flat surface. The center pin only fits one way

And you're done!
