MPCNC Wipers
thingiverse
These wipers help to keep chips from getting between the tube and bearings. They aren't 100% effective, but they do help noticeably. They are designed for 25mm tube. Use glue or double sided tape to fix cloth or something similar on the inside of the wipers. Then snap them onto the tubes and mark the holes on the carriage. Drill and tap those, I am using M3 screws. You have to print: 4xWiper1 4xWiper1_mirrored 1xWiper2 1xWiper2_mirrored 2xWiper3 Wiper1 is for the outer rollers, Wiper2 and Wiper3 for the center.
