I designed this model to manage the poops the printer makes. It guides the poop in the garbage next to the printer. I used the excellent design from thrutheframe but it was taking too much spaces for my liking so I made my own. I took some inspiration from jayburd for the mount. It prints without supports, just slide the part in the other. It can be a bit hard to clip but once done it's pretty sturdy for what it is. You could use glue is you want to make sure it won't move.
Happy printing
