MMU2s configuration suggested extra printed parts?  

RE: MMU2s configuration suggested extra printed parts?

Posted by: @steven-f5

Hello i have recieved my MMU2S for assembly and in the current global environment i was wondering if there are any parts people recomend i print duplicates of in case i break something in assembly. 

I would rather be prepared  in advance in case i cant get  a replacement part printed and shipped while in isolation.

 

i have a mk3s upgraded from mk3  unit

 

Upgrades exist for the MMU2S. Maybe you take a look at this (some suggestions for optimizations):

As you can see that perfect V2.3.1 mod from Karl (which is amazing) it's remixed from more sources and driven to perfection:) To get more info/details look on all this things for inspiration:

• MMU2S-Buffer-M10x1-PTFE_Extension (workaround until you will print/create own REWINDERs)
  • http://www.thingiverse.com/thing:3545935
• PTFE tubes with ID3/OD4
  • order 5m of them and don't use that default for sure
• MMU2 PTFE Holder M10 Passthrough Adapter
  • http://www.thingiverse.com/thing:3233579
• One of repwinders (I use this because I have REPBOX)
  • https://www.prusaprinters.org/prints/6174-repwinder-v214
• MK3s+MMU2s Filament Indicator Cover
  • https://www.prusaprinters.org/prints/2139-mk3smmu2s-filament-indicator-cover

• Prusa MMU2 Selector with magnet and opened FINDA canal

  • https://www.thingiverse.com/thing:3528314
    • But use that E2 modified version from NIMAIM (in comments)!

• MMU2S Extruder MOD feeds

  • https://www.prusaprinters.org/prints/3676-mmu2s-extruder-mod-feeds-almost-any-tip-no-jams-fo
  • PTFE tube 3mm ID -- 4mm OD
  • 4mm Pass-thru couple (PC4-M10)

If you are going to place it in Enclosure you will need these things for sure:

• Slim 90Degree MK52 heatbed cable cove
  • http://www.thingiverse.com/thing:3585029
• MMU2 underslung control panel
  • http://www.thingiverse.com/thing:3211711
• Prusa i3 MK3 Extruder Stepper cooler
  • https://www.thingiverse.com/thing:2975582/
    • No SUPPORT, 15-25% INFIILL
    • Oh and don't forget to buy a 5V fan, not a 12v one! All fans on the Prusa run on 5V.

@kumters

Thanks for the valuable contributions!

RE: MMU2s configuration suggested extra printed parts?

Thank you for all the suggestions.  It looks like I have a few hours of printing before I start this project.  Hopefully my question will help others as well. My mk3s upgrade extruder door cover cracked one side of the axel holder when I assembled it the first time and I didn’t want to find something like that again if it would prevent me from being able to print replacement parts.
