Ender 3 Linear rail bracket X

Linear rail adapter bracket for the X axis. This is to replace the aluminum extrusion all together giving you back that missing range if you decided to use linear rails.

This will fit [MGN12 300 mm](https://www.robotdigg.com/product/766/Quality-440C-SUS-MGN12-linear-rail-with-carriage) rails without sacrifice of any range. It does require M3 and screws and nuts, it also uses M4 screws and nuts as well to attach to the brackets that travel along the Z rail.

Changes in this remix:

- Adjustable screw hole as all printers are different
- Stronger belt tension structure

I have included the Fusion 360 file if anyone want to modify them.
