Spool holders for 18mm rods or 1/2" EMT. Designed for the (Un)Original Prusa Dry Box but could have many other uses.
Holders clamp on the bearings on the inner race and offer clearance for the outer race to eliminate any drag on the bearings.
No supports needed. When printing the Mid Plates and End Plates, make sure that the bearing cavity with the boss is facing up.
The locking screw for the rods should only be tightened finger tight. Using tools may break the spool holder.
