Simple model of toilet for your beloved pets. I use it for pet rabbits without any problem.

I tried to create it as big as possible for MK4S.

Printing

No supports, no brim needed. I tested printing PLA and PETG both went well. After a period of time of usage (for pet rabbits) PETG is far better for this model. I suggest to use 5 or 6 perimeters.
