JD Groove Mount Plate

I couldn't find a groove mount plate that supported the barrel groove all the way around the groove, top and bottom so I designed one that does much better at that.

If the plate thickness is tailored to the groove correctly, it securely holds the barrel in slight compression. The groove might vary between hot ends, so that's why I have cut a pair of shim pieces too, shown in yellow in the pictures.

New for V2 - interlocking shim stock plates. I made the "core" structure with the parts on the right, the parts on the left were made from plastic shim stock to precisely tighten around the groove without damaging the barrel or the mount plate.
