Very cleverly thought out system with the spring mechanism. It works quite well and keeps the adjustment wheels from the print table in the set position. However, in my opinion, the retaining bolt must be reinforced with a small continuous screw, as the spring force will quickly break it off. I printed out and installed this system for both of my Ender3 S1 pro. Compliments to the developer for the well thought out idea.👍😉🇨🇭👍🥂
