Tool to push 608 bearings into their housing.
Avoid damaging your bearings by pushing hard on the inner ring or slipping and damaging the shields. Use this tool to push them home (or tap it with a mallet).
I used this tool to inset my 608ZZ bearings (zz means shields on both sides) into this thing for v-slot extrusions https://www.thingiverse.com/thing:2734638
I drew a sketch, constrained the dimensions and revolved it. Simple :)
Oh yeh, then meshed it and exported it, that too.
