Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2447588.

I had some really small bearings, ID 3mm OD 6mm, 2mm height. And thought Hmmm I should remake the Morse paddle that had melted in my car and use those bearings.

You should look here: https://www.thingiverse.com/thing:2333019 for the original since you might not be able to find the bearings. This is an approximation of the originals melted dimensions, since I don't use sketchup.
