Added a few colors just to see what would happen, used a combination of PLA's (silk, standard, PLA+) and it turned out beautifully! Mechanism works very well, just be sure to actually FOLLOW the instructions and you won't have issues. Completed using P1S w/ AMS, colorization generated much less waste than expected also.

It catches the poo as expected, definitely recommend using with magnets though. Also, if you're doing some heavy color changing, expect to empty or shuffle the bucket every 4-5 hours if not sooner. Been able to use it on overnight jobs, and it actually was backed up to the exit chute because some filament got hung up during purging but I was able to clear it just in the nick of time. Only suggestion would be to extend the height of the rear wall because my P1S seems to violently eject waste at times and it would bounce off the ramp over the rear wall and onto the floor. Doesn't always happen, but as I said, it's the only real feedback I have on the original design. I used MatterControl to build a little riser and glued it on. Problem solved lol. Otherwise, it works and fits nicely on my shelf!

Absolutely fantastic design. Easy print!
