Office Chair Sinking Stopper - (Vitra Physix)

Couldn't handle my office chair sinking over the period of 40 minutes or so, decided to 3D print this simple solution at the height I desire. It clips on easily, and is a littler harder to take off :)

I have the height set for the Vitra Physix chair to have arm rests even with standard heigh sitting desks. The sink lock is 5" tall.
