Quick experiment to compare friction of various arbor types used in my 3D printed clocks.
The options include:
1. Stainless steel bushings with 1/16" music wire arbors
2. Small printed holes with 1/16" music wire arbors
3. Large printed holes with 1/8" music wire arbors
Stainless steel bushings are used in my first clock at myminifactory.com/object/3d-print-136608 They have low friction, but are a lot of additional effort.
The small printed holes turned out to have nearly the same friction as the stainless steel bushings without the additional machining. They are used in my other clocks at myminifactory.com/object/3d-print-137009 and myminifactory.com/object/3d-print-142460
Large diameter printed holes had larger friction, as expected. They might still be used in a few places where extra strength is required and the additional friction is allowable.
