Big thanks to 3D Printbit for their original model - this is a remix of https://makerworld.com/en/models/68962?from=search#profileId-73176
I made this for two reasons. One, I don't really like the chutes where the poop has to travel to the side. Convenient in some ways, but I found heated PLA would get stuck in the chute at times. Two, I liked the idea of a bucket, but all of the models I found were attached at the screw and meant to be reattached at the screw. For me, my machine isn't so easy to get to the back, so I wanted something that was easier to remove when I needed to empty the bucket, rather than fitting it over the screw.
Therefore I designed this as a two piece, with a tray that attaches to the back of the machine, and then a bucket that sits inside of the tray. No magnets or any special hardware needed, easy to remove, and works great. Lots of volume too for those extra big poops.
