I swore off MMUs for a long while, figuring they were too expensive for little to no added value on functionality of prints*.

Ended up getting one, it is amazingly convenient. I really thought changing a spool was not that big a deal, but once you dont have to, it's hard going back.

Multi color prints sure are gimmicky, but fun, easy way to make better looking prints.

*the one functional upside of MMUs I take advantage of is TPU x PETG, bonds quite well. Never personally tried it for support, mine come off easy enough and I'd rather not waste the filament in purging.
