As I did not have enougth space to put the spool holders in the back of my printer, I put then above. But then I had to adapt the mmu2-s-holder-base given in the kit to fit my need.
So mmu2-s-holder-base_rework2.stl basically replace mmu2-s-holder-base.stl : it's compatible with the other official parts which are screwed on it.
And i also made a tube to pass through the wood : it is made for a 6mm hole in the wood, one can put a pfte tube inside (that's how i use it) and its length is adapted for a standart 18mm plank of wood.
mmu2-s-holder-base_rework2.stl must be printed in PET with at least 50% infill (i used 70%). I tried with PLA (and 20% infill...), it broke during a print.
PasseFil_2.stl can be printed with PLA, no effort on that part.
I have a FreeCAD file availeble but it's about 100MB due to initial official stl import and conversion : i'll try to put it there with with no garantee, my connexion is not that fast...
edit 28/10 : licence change to fit to original part licence.
I am not a commercial ;) PET for mmu2-s-holder-base_rework2
50% for mmu2-s-holder-base_rework2
whatever you like !
Put a pfte tube inside PasseFil_2.
