This is a simplified combination of a tie fighter and Darth Vader's fighter. It is nearly impossible to make an exact replica of either, and it be a functional spinner.
Printed it in 4 pieces with the flat side down so it would be a clean print. I provided a complete STL just for for 3d viewing.
You will need:
A 608 bearing
m2 8 allen machine screws
m2 12 allen machine screws
m2 16 allen machine screws
This is my 3rd prototype, and I'm still refining. I had some problems with fill at the bearing arm intersection, and modified the 2nd prototype (shown in picture). Hopefully the thickened junction will fix this, and I will run a print this week to verify clearances.
