A spiraled bearing, to bear a spiraled burden and ease its passage.
I've been printing SiberK's bearings for awhile now, but I had never bound them to the service of the great and spiraled gods.. so here we are.
I built up a single and a double race bearing. What with the elimination of the the layer retractions, these spin real good. Onshape is required and encouraged if you want to modify the bearings for your own projects.
Due to the construction (ie inner wall, ball bearing, outer wall) you get can dictate either inner or outer diameter, but not both. I use regular old 6mm airsoft bbs for the bearings.
