Most of the poop chutes are pretty large and I though i didnt want to waste that much fillament, so I created this smaller one.

Dimensions: 70mm length, 65mm width, 160mm height

It has holes for two 25x3mm round magnets, but so far I managed to use only one that is apparently strong enough to hold it alone.

I printed mine with 0.24mm layer height and 10% rectilinear infill.

UPDATE: 29th August 2023 - as noted in a comment, I made a version with thinner walls as they were unnecessarily thick. This also gives the chute more space for the poop.

The new version has all walls only 1.6mm thick so using two wall perimeters makes them solid. The slots for magnets are kept the same, but I placed a bump in the inside of the chute to make sure the magnets don't fall out.

Even though I did not print this new version, I am pretty sure it should print just fine, as there was not any obvious problem when I sliced it.
