Enclosure Top Plate "R1 for MMU2"

Replace the Prusa Enclosure "Top-plug-edge" cover with a filament passthrough for multimaterial printers with external filament storage.

Edit: The new and updated version has a bit thicker walls ontop, and I shaved a bitt of the back of the bottom to not have it snag on the enclosure when/if opening the lid. I also now include a small clamp for better tube management in the enclosure. (8mm M3 screws work great)

Can be printed in both PLA and PET. I don't think heat will be an issue here.
