Inspired by the Atom, introducing the Atomic Spinner:
Cutting this part is similar to most 2 sided jobs, with 1 additional step:
After cutting the Side A design into the .5" thick material, I used Carbide Create to make the hole pattern.
I kept the holes separate because I wanted to be able to modify them alone just in case.
And It was a good thing- while the HDPE Version was a perfect fit, for the Central Bearing (22.04mm) - The Hardwood version would not allow the Bearing to press in, so I opened the I.D. up an additional .002" in Carbide Create and ran a single full depth "Reaming pass" which was perfect.
Heres a link to ALL the files you will need to make one in all the various forms:
