This is a remix of the original repbox mount that kyle made for the Original Prusa Enclosure to instead take a bar of 2020 extrusion. As you can see, I made this to mount my Filamentalist FV3 units on top of my enclosure for my MMU3.

There are two files, slim and phat. I originally made the slim version but realised the leftover piece of 2020 that I planned to use for this was just a touch small, so I made the phat version.

If your extrusion is 530mm or longer, you can use the slim. If you want more rigidity or your extrusion is 500mm-530mm, use the phat.
