Drone Propellers 2cm

The model contains 4 propellers, two for each side (dimensions: 2cm long), with a 1mm hole to attach them. The hole should be tight enough to mount the propeller without glue. If that's not enough, just add a drop of glue to increase friction. PETG is the perfect material for this print, being flexible yet strong, it can support considerable stress and does not deform at high speeds. An extra tip to improve the efficiency of this 3D print is to smooth the surface of the propellers to eliminate the print lines.
