This Poop Catcher is for the A1 mini!
The 3MF I have posted is for Small Full Kit. It will be 3 prints in total, and should have tree support (auto) turned on.

I have made 4 configurations of the print:
Small Full Kit (245mm) - Poop Box, Tool Box, and Lid
Large Full Kit (315mm) - Poop Box, Tool Box, and Lid (will fit the original tool organizer that comes with the A1 Mini)
Small Box (180mm) - Poop Box only
Large Box (315mm) - Poop Box only

I have also made a Poop Guard, the will make sure the poops drop into the poop boxes. You can check it our here!
