RatRig V-Core4 Funssor CNC XY Joiner modified stop - for post-installation

The Funssor CNC XY joiner is hollow where the X limit switch should hit a stop. Unfortunately, I noticed this issue only after completing assembly and alignment of the RatRig V-Core4 X gantry, rails, toolheads, belts, and wiring up the X axis limit switch…so…..

If you notice this issue much earlier in the build than I did, you can use @Brigandier's stop. This mod of that stop allows the insert to clear the rail and be tilted into place, then slid into the Funssor CNC XY joiner. One advantage of this mod is that it can be removed and replaced later should you either damage it or want to change materials or colors.

The STL contains 2 identical parts, as 2 of them are needed.

Two versions are included:

- PPA-CF version - can be used for materials with little to no shrink. - ABS version - X, Y were increased by 2% to account for ABS shrink. After printing, you might find it desirable to further tweak the X, Y scale in the slicer to get a perfect fit for your material.
