Here's yet another design for a 3D Printer Spool Hub / Holder. This design uses a piece of 8 mm threaded rod, two 0608 bearings, a couple of 8 mm nuts, and two more 8 mm nuts or in my case two 8 mm acorn nuts for a more polished look. The two 8 mm nuts are press fit into the thumb-wheels which are used to keep the spool hubs in place. Don't tighten the thumb-wheels too tight otherwise the spool will not move freely.

The hubs have adhesion pads to keep the arms from curling during printing and it has a small spacer inside to support the bearing cavity. The pads snap off and the bearing cavity support can be removed with an Xacto knife.

No supports or rafts needed because they are built into the design.

The 8 mm nuts should press firmly into the hubs but if they are loose, use some Crazy Glue to hold them in place.

Post-Printing

The hubs have pads to keep the arms from curling during printing and they have a small spacer inside to support the bearing cavity. The pads snap off and the bearing cavity support can be removed with an Xacto knife. The 8 mm nuts should press firmly into the hubs but if they are loose, use some Crazy Glue to hold them in place. The bearings should also press fit into the hubs.
