RE: MM3 and Prusa Enclosure - how did you set it up?

In case anyone wants to mount multiple spools inside the the enclosure, with the option of stowing the spindles out of the way when using fewer spools, I have updated my spool holder model on Printables: https://www.printables.com/model/461663-spool-holder-1kg-or-2kg-for-original-prusa-enclosu

RE: MM3 and Prusa Enclosure - how did you set it up?

I've now uploaded a 'kit' of parts to help with mounting the MMU buffer on the underside of the enclosure hinged lid: https://www.printables.com/model/845863-mmu3-mounting-kit-for-original-prusa-enclosure

It includes:

  • Mounting feet that take the place of the buffer plate holders
  • Filament guides with multiple feed points for the left and right corners
  • PTFE clips that grip the PTFE tubes a little tighter, with options for fixing the clips to the enclosure
  • A revised thermometer mount to allow for the left-mounted filament guide.

Looks great Chris. Will give it a try, once my MMU arrives. Might still take some time, since I ordered in march this year.

In the meantime I am assembling the (un)official Prusa drybox. I am modifying the fixation to the enclosure such that:

  • the fixation + drybox is compatible with the hinged lid mod
  • the drybox is fixed horizontally in positon (x-y-axis)
  • the drybox can easily be taken apart when opening the lid (z-axis)
  • the position of the drybox on top of the enclosure is adjustable

Will upload everything to Printables when everything fits.

RE: MM3 and Prusa Enclosure - how did you set it up?

I've changed my setup slightly - I now have the buffer on top of the lid, rather than slung from the underside.  I realised that the lid could no longer be used as a shelf anyway, since it had to be cracked open to load filament, or fully opened to access the MMU unit, so there was no real benefit in having the buffer inside the enclosure.  Using the same brackets and PTFE tube lengths I've now mounted the buffer on top, which means I no longer have to open the lid to load filaments, and the danger of the tube from the MMU to the Nextruder fouling the buffer at high Z positions has gone.

In this configuration, the bracket set that centres the buffer on the lid is preferable to the set that moves it 30mm back, since this gives a gentler bend radius for the pipes between the buffer segments and inside of the enclosure.

The 10 pipes virtually fill the hole in the rear centre of the lid, but I will probably now make a piece that replaces the blanking plug and allows 10 pipes to pass through without any gaps.

I added a pass-through top plug.

I went with the Mohawk mount.  It works well for me.

During my first test, my filament box worked perfectly with the inserts.

I have uploaded the insert here on Printables.  Whether it will work permanently remains to be seen.

Maybe it also works without a filament buffer.

I will use 5 individual drying boxes with an insert to prevent tangling. I don't know yet whether it will work.

I gave up using the Prusa buffer almost from day 1 on my MMU2 as it took so long to load.  I'm using a Lack enclosure with a Mk 4 and MMU3 but will be upgrading to a Prusa enclosure.  I use a set of filament auto rewinders (loads of different versions on Printables) and they are really good.  You can change a spool and be pronting again within seconds.
