While building my Lack enclosure, I noticed that, when following the official instructions, the Bowden tubes leading to the MMU buffer would kind of just... dangle there, and you'd have to remember the order in which they'd end up arriving at the MMU. Since me and remembering things doesn't mix, I made these!
It's as simple as it looks: A couple of funnels, with a hole through them and some wings to screw them down. That's it. The holes in the back of the funnels are sized to take these M5 heat set inserts by CNCKitchen, so that you can attach an M5-PC4 pneumatic connector to them.
In order to make it even more impossible for me to mix the inputs up, I added the tags. They slot into the funnel part with a simple mortise-and-tenon fit. I used some superglue to attach them together.
Since one of my filament holders doubles to lead not only to the MMU, but also to my MMU bypass, I made a double funnel, and added a tag reading "B".
There's also a blank tag included, if anyone wants to make their own.
Printing can be done in PLA, since the funnels will most likely not experience any heat or major friction. I printed them with the wide part facing down. I don't think I needed supports for the funnel interior, but ymmv. The attachment wings needed supports though.
Feedback is always appreciated! Happy printing! :)
(I'm sorry for the awkward angle of the pictures! The filament holders were in the way lol)
