Multirotor Motor Grippers

NinjaFlex is pretty darn sticky when it's printed on glass and used on smooth surfaces.

Print these out and use the glass side to wrap around you mutlirotor's motor bell to help tighten and loosen those darn prop nuts.

Three sizes are available:

Small - 1306 size (or any motor with a 20mm dia or less motor bell)
Medium - 1806 size (or any motor with a 25mm dia or less motor bell)
Large - 2204 size (or any motor with a 30mm dia or less motor bell)

Should be able to be scaled to fit any sizes bigger.
