Intro
====================
There is an old saying, "Don't reinvent the wheel". However, if we never reinvented the wheel, we would still be stuck in a Fred Flintstone society with Fred Flintstone Cars yabadabadoo'ing our way down town, walkin' fast, faces pass and we're homebound. So therefore, I am literally reinventing the wheel. Here is the latest technology in print in place bearings.

Version 2
====================
Second Version is just a few touchups. The basic one has a clearance of 0.1 mm, the one with a tighter clearance has a clearance of 0.05mm. A 6 roller variant was also added for people with printers that can't print a 0.8mm rod.
Printing Tips
====================
Remember, if your prints have elephant's foot, then this tiny bearing obviously will not work after printing due to parts fused or warped geometry. So if you never tuned this issue out of your printer, print with a raft. Remember this is actually a pretty difficult print with a number of small parts, it will be advisable to print slower just incase. That being said, my ender 3 pro handled this print with pretty standard print settings.
Other tips include changing Z-seam alignment to random and also lowering flow rate.
It is very simple to free this bearing. Hold the center, and roll…
