MMU3 - How to keep filament slack dry in buffer
For folks such as myself that don't print with all 5 filaments daily, I was curious if anyone cares about the fact that the slack in the buffer is just sitting exposed (potentially for long periods of time)?
I suppose I could just unload 3ft of nylon to get to the stuff that's been sat in my drier box for weeks, but seems wasteful. Or fully unload the MMU3 slot when material is not in use... but I'm lazy and like the idea of just hitting a button to switch from PETG to Nylon and letting rip. Has anyone seen a fully enclosed buffer solution before I head off and think about designing my own?
I guess the other way I could possible do it is to find a good buffer-less retracting spool solution.

I put the buffer in the dry box with all the spools. Needs a bigger dry box, but 1/3 to 1/4 the cost of many commercial ones. I tried the retractors and clutch reliability was bad. The gravity ones seem better, but also take a lot of room or a big dry box in the end. I like this since I can put 2KG spools in also.
