Litter Robot 3 Carpet Feet - LR3 Feet extensions for weight sensor on carpet

thingiverse

These leg extensions add 8mm to the bottom of the Litter Robot 3 Open Air's feet, making the weight sensor perform better on carpet. The prints are made with 2mm layers, 15% infill, and a 1mm shell using PLA. Printing this design takes approximately 2.5 hours. Layer height is set at 0.2 mm, while infill percentage stands at 15%. A 1mm shell adds durability to the model. In my case, a smaller cat would often fail to trigger the weight sensor due to our apartment's wall-to-wall thick carpeting. With these upgraded feet, the weight sensor now operates as expected, even for both cats. As an additional tip, when attaching the feet, some users may find it helpful to apply white "Tac" museum putty to keep them secure while being moved around. However, this step is not necessary. Print Settings Printer: Maker Select 3D (a similar model to the Prusa i3, produced by Monoprice) Rafts: Irrelevant for this print Supports: Not required due to the printer's capabilities Resolution: Set at 0.2 mm for high precision Infill: Standing at 15% for a good balance between strength and material usage As for specific printing parameters, note that the model has an overhang on the largest disk, but it turned out great even without any support material due to my printer's advanced capabilities. Additionally, I applied white "Tac" museum putty around the feet to keep them secure during transportation. This step may not be crucial but helped improve stability nonetheless.
