I kept breaking the spinner cap on my E-Flite Apprentice. I would have to pay $5 each time and wait for it to be shipped out, then I remembered that I had a 3D printer. I just recently uploaded the base as well. The two pieces are designed to snap together and each piece should be compatible with the OEM parts.

I printed in both ABS and PLA+, both materials seem to work fine. I had to use supports to print the base of the spinner. Happy flying!
