I've made some chair legs caps as i had issues with the factory ones, they were way to hard and generate lots of noise when kids were pulling/pushing chairs so this way sound is almost inexistent and they also offers a great friction and stability.

I've printed them with eSun TPU 95A orage translucent with 0.4mm nozzle and 0.20 layer height.

The profile also has a modifier to use 50% infill for first 10mm height and 15% infill for the rest 10mm height. I've chosed to use 50% infill as the base has to be solid and support the chair pipe legs without going through the cap.
