RC 2 or 3 blade prop spinner
thingiverse
The 3 bladed prop spinner is designed with GWS 8x4x3 prop specs, while the 2-bladed prop spinner is designed with APC 8x4.5 MR prop specs. I designed these specifically for my FRC Lancaster RC plane. Spinner top is attached to the spinner base by servo screws. The 1.5mm thick washer plate is optional for clearance, if needed. Print only with 1 perimeter for all parts and 10% infill for just the base plate and the washer. Approx. weight is about 6-8g only! Credit: The base was designed from scratch however, the inspiration was taken from this thing here so it should look pretty similar with reduced weight: https://www.thingiverse.com/thing:44872
