I added nubs to the bottom to keep it from moving on the carpet. Unfortunately, this made it so you have to print it on its side and with supports turned on. I am thinking of another remix to help with the supports, but that will require some additional changes.
Also… my massage ball I got from the Relax The Back store. It was slightly larger, so I have to upscale it in the slicer by 5%
I printed mine on an Elegoo Neptune 4 Pro. I would have printed on my MK3S, but it would have taken way too long.
The author remixed this model.
