Skull and Bones spinner

Co-worker wanted a Skull and Crossbones stylised spinner, and this is what I came up with.
Made for the following hardware:
1x 608 bearing
4x 8mm or 5/16th nuts

These will press fit snugly, and the skull caps will lightly press fit inside the bearing.
The skull is best printed face-down with dense supports with a nice separation distance - it will let the support pull out, and leave a nice texture on the skull (another photo coming soon).
