The leg is adjustable from 91mm to 120mm.
If the printer has a well-calibrated flow rate, the thread should rotate freely and the leg should fold with slight resistance (so that it does not fall out when moving the furniture).
He also designed the handle for the leg cover.
Secure with standard 4x16 screws.
I recommend printing with PET-G.
ps. I have a wardrobe with three large drawers on these legs, fully loaded and nothing happens.
