I wanted a chute to direct the poop into a bin that I could empty easily. I needed it to be narrow so that it did not require any more room behind the printer than the power cord sticking straight out.
I printed it with PLA using the standard P1P settings. I printed it with the flat end down. That required no supports.
It is pretty fragile, because all I cared about was quick and simple. I super-glued 15x2mm magnets in place and they are just strong enough to hold it in place, but I already had them.
The Fusion 360 model is included if you need to make modifications.
The author marked this model as their own original creation.
