Since some users were having issues, I added a cutout under it, to make sure that the cover isn't touching the two screws that hold the build plate.
This cover is designed to prevent dust and filament debris from falling into the small space between the bed frame and the rear axis.
It also acts as a third build plate guide in the middle.
It is 100% compatible with all printer movements and will not interfere in any way when installed on a P1 or X1 series printer.
Remove the build plate : Remove it to access the space under it. Remove any filament debris that might be stuck.
Snap the Cover In Place : Simply position the cover without applying excessive force, it should snap in easily.
Check for Gaps : Ensure there are no gaps between the little walls where the cover rests and the cover itself on each side.
Put the build plate back : The build plate should slide smoothly on top of the cover
Once you’ve completed all the steps, your cover is now ready to go!
