Ball Feet Add-on for Décathlon's Quechua mh500 chair

Here's my adaptation of Peter H's ball feet to the cheap copy Decathlon made of the Helinox chairs. The original robber feet sink in everything, but I still wanted to keep them on my chair. So, I made use of the hexagonal shape of the original rubber feet to make an add-on version.

28/06/2022: I printed the feet already, but still didn't have the chance to try them yet. I'll try to bring the chair with the ball feet to my next camping trip, as in my region, almost all soil is sand. I think I'll ameliorate this page once I'm sure they prevent the chair from sinking.

30/08/2022: Tested the feet on hard pack sand/gravel, and I didn't sink! Now I want to test on fluffier soil to see if the circumference of my feet is large enough.
