Designing a 3D printable bearing as a test for dual extrusion.
I wonder if dissolving in a vibratory chamber might help reduce design requirements. ?
I agree that this obvious use of dual extrusion has not been explored enough. Let me know if I can be of any help.
I do think that the first thing to do is get your machine dialed in to the absolute best tolerances. Maybe you have already done this. I am just thinking that the part will have to be perfect when printed to render the best results.
Another thought is that polycarbonate might be a better choice for your main material- it would be better suited for the heat and pressures that a bearing will need to endure.

I actually used a small windscreen wiper motor every now and then to blow fresh liquid through the middle of the bearing. I have thought a vibration chamber might help out in this regard.
The printer was calibrated right before the bearing was printed, since then I have changed the mounting method for the extruders which should keep them a bit more stable.
Haven’t tried printing polycarbonate, will have to add it to my todo list. From what it sounds like it would be an ideal material for this.
Does that bearing work
Yeah, I can use it on a filament spool even though one of the rollers has broken apart.
