Ender 3 Pro X-axis MGN12C Linear Rail Guide Kit with Fix Plate Mount Bracket for Ender3 Ender 3 V2 3D Printer Upgrades (X Axis, Without Rail)

The other reviews saying the holes are wrong, got a MGN12H instead of a MGN12C linear rail. H is 20x20, C is 20x15. I think this took about half an hour to install and I was able to reuse the stock belt.

So first my linear rail was 20mm by 20mm hole offsets. Just drilled two new holes not hard. but I hate the open back where the belt loops around. makes it so the belt slides off.(mine also has 2 slits one each side, not a problem just not shown.

The 4 holes in the plate for mounting to the Linear Rail were wrong.It may fit some. But to make this part fit more rails.You need to add two holes.Mine was 20MM by 20MM square.

This product works well if you’ve converted to linear on your Ender 3 v2. However the seller should have mentioned that it lacks the required mounting holes for the bl-touch. I had to manually drill holes to make this work with my bed leveling. Who doesn’t have auto bed leveling at this stage in the 3d printing game.
