OptoFlag for FlashForge

thingiverse

Upgrade your 3D printer's Z endstop with an innovative optical sensor. This easy solution requires a flag to trigger the switch, which will seamlessly replace your traditional mechanical stop. Simply attach it to the threaded Z shaft and enjoy hassle-free printing sessions without worrying about bumping or interference. The idea behind this design was sparked by a similar concept on Thingiverse: 976727
