Ender 5 Plus Locking Bed Knob

Inspired by AJCam44's solution because it offered the most fidelity of adjustment. Thank you very much for your solution which has served my Ender 3 S1 very well. This model adds the following features: 1. Locking mechanism suited for Ender 5 Plus 2. Reduced radius of bed wheel to not obstruct bed rod/rail 3. Increased bed wheel height to support heat insert 4. Redesigned retention spring mechanism to provide symmetrical locking force Remixed in Blender since I have yet to learn parametric modeling. Printed with PETG no supports
