Description
So I found a way to print some bearings up. I am working on a project that requires alot of bearings. But I was annoyed that I can't print any bearings for the project.
I use the filament itself as the ball bearings. But since the filament is a rod the bearing is a little tall. You need to make sure that you cut the rod to the right size, if they are a little too long, they will rub on the end caps. If they are short, they will rotate sideways and jam up the whole bearing.
When I was trying the first design the bearing was spinning, but not loose. So I ran it on a tamaya gearbox to break it in. After about an hour of spinning on that I got a fine white abs powder inside and it was running much smoother. After it broke in, I cleaned the powder and filled it with Vaseline.
Then it was perfectly smooth.

These are cool! how smooth are they, and how much wobble is there? Also this is more like a roller bearing than ball bearings.
There is not much wobble from the bearing it fits together pretty tight.
The smoothness depends on how you print it. If you have any lumps and errors in the print, it won't spin well. But you always get them, so I filed them down till it was mostly smooth. Breaking them in by spinning them also helps.
