About this 3D model

My entry for the 3d printing nerd design challenge. A fairly simple rollholder for Joel's spool shelves.What you need: 2 x the printed rollholder 4 x 608zz bearing 4 x M8 bolt+ nut Mount the bearings in the holders. Put then in a suitable place on the shelves. Then place a spool on the bearing rollers. That's all.
