thingiverse

Thing Files helps you to upgrade Ender 3 x-Axis guide from original rubber bearing to MGN12H linear ball bearing rail. This Thing includes: - Track installation guide. Useful to center the rail to the X-axis profile - The belt anchor prolonger to keep belt aligned whith recess profile - The side block to prevent the moving block goes off the rail BOM: - 1 x MGN12H 300 mm linear guide (track and rail) - at least 3 x T-nuts with 3MA thread and socket head screws for the track - 4 x 3MA countersunk head screw to fix the block to the plate - 1 x 3MA T-nut and socket head screw for the side block. You have to make four countersink holes in the X-axis plate This upgrade reduces the service time and makes more rigid and precise the x-axis. It really works for me!
