Description
It is a bearing that I tried using a combination roller to improve the roller falling off and rattling.
Since there are many rollers, it takes some time to remove the sticking between the rollers, but if you remove it patiently, it will rotate well.
UPDATE 04.08.2021: Replaced with data that is a little easier to print
UPDATE 04.17.2021: Added data with holes in the outer shell to insert a precision screwdriver and remove the sticking between the rollers.
