Inlay Spinner v2

Rounded off the corners since the v1 corners were super sharp and tearing up my fingers.

Also reduced the size of the inlays by .5mm to try and prevent cracking since v1 seemed to want to break when inserting bearings.

All other aspects are the same as v1.

Marking this one as WIP so that if I do end up with a v3 of the same inlay style I will just update this one instead of marking a remix and uploading as a new thing.
