Simple solid bearing 608
thingiverse
I tested a lot of bearings from this site but they cannot be used for 0.4 mm nozzle because of 3d printer limits - small cylinders cannot rotate normally, big gaps between parts and so on. So I decaided to creat a simple solid bearing with minimal number of moving parts that can be used in the most home hobbies and 3d printer parts without big issues. It has good stability. I also recommed to use a grease to improve movement and rotation.
