A 3d printed MGN-style linear slide bearing

 Ive decided to make my own linear rails when i saw prices for a good quality MGN rails.
 I hope that this project will allow more people to tinker freely without spending a fortune!

 
This project features all MGN rail and block types
  • MGN7С/MGN7H
  • MGN9С/MGN9H
  • MGN12С/MGN12H
  • MGN15С/MGN15H
With different clearances
  • 100 micron
  • 200 micron
  • 300 micron
 
Just select a rail type, block size and desired rail length, print rail and carriage block rated for same block-rail clearance and assemble them!

 

More detailed instructions for printing and assembling the rails are provided in a file below downloadable models

Happy printing!

P.S. I also really wanted to release curved linear rails, but it seems that the Fusion 360 doesn't have tools to make that without selling your soul to the devil. I've included the CAD files. You know what to do...
