MGN9 to 20mm V-Slot mounting surface plate/rail

MGN9 Linear Rail ever so slightly sits in the v-slot of 20mm v-slot extrusions due to the chamfers. Common t-nuts can't clamp down on a 20mm v-slot rail enough and as a result the rail is not held 100% secure. Additionally the chamfer on the linear rails can't be considered a reference surface and may cause issues with spacing or laying flat against the extrusion.

This simply gives the 9mm linear rail a mounting surface on top of the 20mm extrusion. Compatible with LMaker's KP3S linear rail mod with no additional modifications required.

Model is compatible with the slightly longer t-nuts some have encountered.

I used PC filament with a 1mm thick bottom layer resulting in 100% fill in the location needed.

Do Not use a filament that exhibits creep, PLA is a no-go.

Print a set of 4 for the full LMaker mod.
