Or they get stuck in the Triangle Feeder (see pics below).
It’s mostly 3D-printed (the dog bones were from the failed vibrating feeder – ABS plastic, iirc) with the grey triangle being resin printed. Those black brushy things are false eyelashes lol (thanks Theresa!). This whole thing is held together by superglue.
If we can solve this issue by the end of this week, we could potentially meet our goal of sorting 1.5 marker bands per second!!!
