Background:
My father is a softball umpire and he has always complains about his indicators tearing up his thumb/fingers over the course of a long day with tournaments or double headers. I modified this AMAZING design by Ptarmigan to use magnets to hold the indicators in place. I used 13, 6mm wide by 2mm thick magnets. These are the magnets I purchased and they worked great. https://a.co/d/3W3x1Pc
Printing:
I paused the print just before the magnet holes get covered. For the dials, it was layer 17 and for the back casing it was layer 36. Please pay close attention to the orientation of the dials and backplate when you print so that you install the magnets in the proper directions!
I used PLA, 0.2mm layers with a 0.4mm nozzle.
Otherwise, I followed Ptarmigan's incredible detailed print instructions! Check them out.
*NOTE* 2/2/2025: This indicator has not been used in the wild yet! I am unsure how well it will hold up to normal use or if it may be susceptible accidental turning of the dials. My father plans to test it out in some upcoming scrimmages and see how it works and if it holds the count.
I do plan to modify this design further by removing the gear teeth on the dial and having some notches instead.
