Nuclear spool adapter with 608-2Z bearing
thingiverse
Standard spool adapter that uses a standard 608-2Z bearing. Could not find the one i saw at some point, so i spend 5 minutes recreating what i recalled from it. Pressure fit the bearing and then secure the whole thing with some nuts to your threaded rod. Note that the bearing can easily be removed later by prodding it with a something pointy from the other side. Inner diameter of this is 8mm, same as the bearing inner diameter. Fusion 360 source available on request.
