Ender 3 X axis Cover and limit switch for MGN12H

After adding MGN12H linear rails, the limit switch on the X axis has to be 8mm higher. That means, that the stock stepper pulley cover has to me removed to make more room for a custom limit switch adapter.

Pulley Cover :

I created two versions of the new cover.

- Cover that just clips on the heads of M3 screws with 5,4mm diameter - → Aestethic look, but could fall of - not recommended - Cover that will be screwed into the existing motor mounts with M3 screws - → sits firmly, cannot fall off - recommended There is a small slot to route the limit switch cable to the top.

Print orientantion :

The cover is designed to print without supports in the orientation shown below.

Adapter :

Credits to @Tzach adapter, i just shimmed the V nut a little to make it fit with standard M3 T-nut's.
