It works! Opted to also use the Remix to allow usage of the bearings included with the kit: https://www.printables.com/model/62798-mmu-buffer-mod-for-prusa-mmu-bearings

Overall, its going to allow for greater personalization of the MK4/MMU3/SUNLU4spoolDryer footprint.

Thanks for the design. Sparks the creativity! Cheers!!!

I had to make some modifications. I am using 6805 bearings, it's what i have, and i am mounting them on the wall below the spools of filament. I printed one out and tested it. I am printing out 4 more. They will be done sometime tomorrow and i will put them to work.

cool but it should be an all in one, so you don't have to buy bearings, It would be nice if it was an all in one. Thank you :)

Nice straight forward print, made 5 out of PLA (one gray one because that was the end of that roll).

I screwed them directly into the top of my drybox and the PTFE goes all the ay in reducing friction.

To solve the jamming problem I slipped some thin acrylic sheets between them which helps keep the filament vertical.

Has anyone foudn other solutions for that jamming problem? I don't currently have enough space to set them far apart or as Jarcec has put them (see comments). Tried janking something between each buffer roller, but filament slips by those so I currently don't see any other way than enclosing each, which defeats the purpose for these.

@OeschMe I bought some 1 foot square pieces of thin acrylic on Amazon, then threw together some little feet and puth the sheets between the buffers, it keeps the filament from looping over into adjacent paths.

would have been nice if it fit the bearings that came with the MMU. I've made a "remix" that includes parts that will make this buffer compatible with the bearings that you should already have from the MMU package.

I can confirm the jamming problem described in an earlier comment. When the filament unloads , it's too long and since it's naturally twisted from the spool, it twists itself over the next wheel. Which then on loading the other wheel tangles everything together sadly.

To space everything "safely" the wheels must be at least 12 cm apart from each other as far as I can tell. (edited)

Yes it does tangle indeed. I was planning to space them tight togheter but with a plexi or other surface between them, so the filament is forced to go straight up.

I apologize for really late response here. After few iterations, I've ended up with the following spacing that works great for me.

Thank you for the model @MaximeL_89691 !

i put five on a line, and i got in trouble. The parked filament felt on the one i used, so after a change one got under the other, and jammed. So to be honest, the buffersystem is only useful when you have enough space, that the kloops have enough space between. Maybe it is a good idea to thing about a cage?
