I'll print it in clear PETG with 99% infill.
Adjusted the heights to fit my RH Logic 4 chair which is a bit high with the original. Here are 3 different heights with a 1 cm spacer as well.
The author remixed this model.
A simple re-make of the original, with several different heights (40, 60, 80 and 100 mm) and a 10 mm adjuster. Copied into Tinkercad and adjuster and placed on the same plate.
