Keychain Mechanical Counter
prusaprinters
<p>A small mechanical counter I designed for archery. Can be attached to a keychain. Will count up to 99. Gears work so the decimal wheel will automatically turn when you go from 9 to 10, 19-20 etc.<br><br>You will have to adjust the orientation of some of the parts so they print properly. For the case you will need to use supports for the keychain hole. <br>You can use the the images or the STEP-file for assembly. Don't forget to add the second spring in the top half of the case before closing. I used a little bit of glue to hold the springs and the 2 case halves in place.</p>
