MMU2/3 Wallsetup

Here is my version of the MMU3 setup. My version uses the enclosure for the mk3/3s/4/4s but it would also work without it. It consists of two brackets which can be screwed to the wall. One with 2 holes for the PTFE tubes and the other only for spools.

Then simply print 2 of each and mount them slightly offset from each other (see picture). 

I have the 5 spool here in my Sunlu dry unit. I used the wall bracket from: Ankhadia Sunlu / Tecbears Fila Dryer S2 - Filament Trockner S2 Honeycomb Bracket von Ankhadia | Kostenloses STL-Modell herunterladen | Printables.com and the dryer holder itself from: Johination Sunlu / Tecbears Fila Dryer S2 - Filament Trockner S2 von Johination | Kostenloses STL-Modell herunterladen | Printables.com. 

If you don't have a dry unit, you can simply print another holder. 

In case you want to make adjustments to the models I will upload the STEP files as well

The buffer unit is attached to the enclosure with the model from:

I printed the wall bracket from PETG with 15 infill. But PLA should also suffice

Have fun printing and building
