I designed this mount for the MMU2S, RMU style buffer.  Shown here, https://www.printables.com/model/77054-mmu2s-buffer-inspired-by-rmu-buffer

It is designed to mount the buffer without modifying the buffer bottom.  It fits the outside, right, left and possibly back side of the Original Prusa Enclosure. in the middle of the rail. Mount holes  for the enclosure are slotted to allow height to adjust as needed so it will sit on the same surface as the enclosure.  

The bottom of the buffer can be unbolted and rotated 180 as needed to move the mount to the other side.  

0.3mm PLA, 20% infill.  No supports needed when printing with the bottom on the platter. 

Step file included to allow remixing for 90 degree or different orientation as needed. 

Screws needed

2  3mm x 16mm or longer for mounting the buffer.

2  square nuts for the capture nut holes in the mount

2  3mm x 20mm bolts for attaching the mount to the enclosure.

2 Washers recommended for the bolt heads where they go in the slots for attaching to the enclosure.

2 3mm nuts for attaching to the enclosure.  Locking nuts recommended.
