These are a portion of the files from https://blog.prusaprinters.org/mmu2s-printer-enclosure/ that have re-arranged/modified for printing on a Prusa Mini
It doesn't include these parts because I assume you are enclosing a mini and don't need them:
The parts of the U-frame that are too large to print on the Mini have been divided into 2 pieces and I've added alignment pins/holes to help when gluing them back together.
I printed this in PLA and it's been working just fine, though the blog post recommended PETG. Follow the rest of the instructions from the blog post for assembly
The author remixed this model.
