Shelf-Mounted Spool Holder for Prusa MMU2S / i3

Well...it's been the usual situation:

Got me a Prusa i3 MK3S with MMU2S and had only limited space on a shelf.

I totally liked the original spool holders and the buffers that come with the MMU2S as well, yet I just didn't have enough space, so I decided to re-use those parts of it that I really liked the most and redesign the rest on my own.

So I designed this shelf-mounted spool holder for 16mm boards that uses the original bearings and aluminium rods to clip-in. The rest I just tossed.

Since I am a lazy sloth, further more I created me some drilling template.

To attach the PTFE feeding tubes of the MMU2S to the shelf too, I also added mounts for PC6 fittings. This saves you basically from using the original filament buffers.

How I Designed This

So how did I design this?

There's only one word that describes it perfectly: "messy"
