Propeller Shaft Bumper for Multicopters

thingiverse

Print them in flexible material!\nWhen you're prone to landing upside-down like me, printing some bumpers can safeguard your propeller shafts. These bumpers snap onto the washers that secure the propellers and can be effortlessly removed for the inevitable prop swap. I'm uncertain if these washers are standardized, but my Sunnysky 2212 motors feature washers with a diameter of approximately 14.75mm or .58". For anyone needing to customize, I've included the Fusion 360 model. Each bumper requires about 1 meter of filament.
