This is a spinner for the P-38 lighting from Flite Test. It's a remix of the RC Plane Spinner by novakclast (https://www.thingiverse.com/thing:2643257) altered for 3 blades and re-sized to fit the FT P-38. As the props counter rotate on this plane you will print two of the "Base" parts, mirroring one of them to get the other direction. The "BaseS" part is a 3mm shorter version of the base. I've also provided a 3mm shim, in case you need it, to space your motor further out. You can print that as thick as you want by altering the Z height of the part in your slicer. I needed 4mm on my left motor. These should match up well with my air intakes for the same plane (https://www.thingiverse.com/thing:5827003). Use three M2 screws per spinner to attach the tips.
