Litter-Robot 3 step ramp for small cats and kittens
A step that sits in front of a Litter-Robot 3 or Litter-Robot 4 and lowers the jump into the globe, which is around 250 mm off the floor and too high for a kitten, an older cat or a Munchkin. The step is 300 mm wide, 250 mm deep and 110 mm tall, hollow with 2 mm walls and internal ribs on a 40 mm grid, with a textured top surface and a 5 mm lip that catches litter tracked out of the globe. Four 25 mm pads underneath take rubber feet. Print it top down in two halves joined with 6 mm dowels, or in one piece on a 300 mm bed.
Step heights and widths depend on the cat and the space beside the unit, so a generated step fits your room and your animal. In SpeakCAD you give the width and height, preview the step in the browser at no cost, add a litter-catching mesh to the top in the chat and download the STL or 3MF.
Model a hollow pet step 300 mm wide, 250 mm deep and 110 mm tall with 2 mm walls, internal ribs on a 40 mm grid, a 5 mm rim lip, a 1 mm textured top, four 25 mm recesses for rubber feet and a middle split with 6 mm dowel holes, for a Litter-Robot 3.
