I love this design, thanks for making it! Unfortunately, I need to store my filament below my printer, and the arms (as designed) keep pointing the filament down as soon as the backfeed accumulates. Could you possible make a remix with the arms secured to the mount rotated 180 degrees? I tried doing that with the current version, but the parts don't align correctly. Thanks!

Are you connecting the Prusa ptfe feed tube from the back of the MMU2 to the push fit connector on the arm?

Never mind. I connected mine after I realized without it it didn't feed right.

hey stbw_9238, this is my Z axis cable snake cam mount with octolapse to make it look like a bed mount. Z mount means it raises with the head/print.


jdnza, wow, nice work, looking good. When you say reverse direction do you mean the flipflop device is upside down?

I am working on my own FW too if you get sick of PRUSAs attempts.

Works brilliantly, cheers mate!

I did reverse the direction as I have the filament under my printer

I was just wondering what camera holder are you using for your videos ? I've been looking for a bed mount system. Thanks !


Thank you, yes it is working great, not a single issue since. I have three larger prints done, 18h, 13h, 14h and a few smaller prints done since.

Hopefully we can all get it sorted and make some awesome prints

Fantastic - will upload pics of my makes when done :) Cheers!

Rob, this is brillant - EXACTLY what I'm looking for. I'm currently printing the same spool holders and will be using with Lack in an identical layout, I was about to design almost exactly the same piece you've uploaded here - is it working well?

Great work, saving people a lot of time and hopefully providing an excellent top-fed lack solution for MMU 2.0!
