608 Simple bearing with lubrication ports
myminifactory
It's a reupload from my Thingiverse account since their site lost some of my designs, I'm moving to MyMiniFactory. Simple bearing without any moving parts other than the core itself. It is printed in place and needs some force to unlock after printing. I had troubles with other printed 608 bearings like bits breaking or seizing, and wanted to have something simpler. It requires lubrication for smooth movement. It has 2 lubrication ports which can be used to inject grease. You could seal or leave them as it is after initial lubrication. Designed for vertical operation, it would have more friction horizontally. It should be printed on a raft to avoid elephant's foot (horizontal expansion) due to squish seizing the first layer.
