I used 0.2 with a 0.3mm nozzle Infill:
N/A Notes:
The two hubs should be printed with the “flat” side down. You may need to use a raft if you get a lot of “Elephant Foot” on your first layer. The prints I have made usually needed to have a few of the roller bearings broken free so everything turns freely. If you have trouble with the bearing sticking together, try lowering the extruder temp and/or reducing the filament flow rate a bit.
I included a cover for the M8 nuts typically used. For these, pause the print at 6.8mm and drop the nuts in, then let it finish.
Post-Printing
Assembly:
Press the hubs into the spool with the spacer between them on the threaded shaft. Snug up lightly with the knobs and place in holder.
