About this 3D model
I was getting ready to assemble the wonderful Pastamatic spool winder and figured it'd be nice to have a bushing to use with my arbor press to seat the 608 skate bearings, so I whacked one up in TinkerCAD. I imagine it could be used for tapping the bearings in with a hammer as well. If you dig my model, please post a pic of your finished print. It's fun to see other makes!
