Complete linear rails conversion of CR-10 3d printer
Full conversion of a CR-10 3d printer to linear rails. On each axis I have 2 linear rails, including the X-axis. This is not needed, however I decided to do it for more rigidity and to be able to attach heavier direct drives. Here are the linear rails I used:
Y-axis: 2x500mm MGN12 w. 2 H carriages
Z axis: 2x 500mm MGN12 w. 1 H carriage
X axis : 1x400mm MGN12H 1x400mm MGN9H
I bought the rails from RobotDigg and Hiwin (MGN12 on the X axis) and I am very happy with their quality. There are cheaper rails and maybe they are OK for a 3d printer, but I didn’t want to risk with noname brands.
Check the linear rails prices:

Aliexpress: or here for Hiwin:
For black oxydized linear rails check the ones from RobotDigg I used them om my DIY Voron Switchwire 3d printer shown here , and they were quite cheap for the quality.
Other parts and printed parts:
