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.

Fit notes
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, add a litter-catching mesh to the top in the chat and download the STL or 3MF.

Yes. SpeakCAD slices the part on its servers with OrcaSlicer and your printer's official profile (380+ printers, including Bambu Lab, Prusa, Creality and Elegoo), and you download the G-code (a sliced .gcode.3mf for Bambu Lab printers). G-code sliced for your printer costs the same as the STL: included in every plan, free for a part you shaped by hand, 4 credits without a plan for a part with AI work in it. Pick your printer on the printers page to see its profile.
No. SpeakCAD runs in the browser on your phone or computer: the chat, the 3D engine and the live viewer load in the tab. The only file you download is the finished STL, 3MF or sliced G-code.
