This is a printable cat litter box mat I created to catch loose litter that falls out of the cat litter box. It is easy to clean and does not start smelling over time.
The mat uses a serving tray as base. The uploaded parts are designed for a 41 cm * 31 cm serving tray with rounded corners.
The full build process and parts list is described here.
Each of the three parts needs to be printed twice.
