Thanks for the writeup! The mmu3 assembly instructions do mention I need longer PTFE tubes if I want to combine it with the enclosure, so I dont think there’s avoiding that. We’ll have two enclosures with MMUs next to each other, so having the spools hanging on the outside feels a little too unsightly.

I’m eyeing the (un)original drybox too, but it’s adding quite a bit of cost.

And hardware upgrades.

Do you have any advice on putting the spools inside the enclosure? I haven’t put our MMU3s together yet, but all the official photos show the spools on the outside.

Most of the CAD software mentioned here will not be super helpful in modifying meshes (like STLs), but they’re great if you want to redesign the part from scratch :)

Tinkercad is the exception, as it works with meshes and booleans.

OK, but why is Leonard Cohen walking into an Apple store?
