Ender 3 level knob clip

thingiverse

The stock ender 3 level knob will move with printing. Previously use a red dot sticker to mark the position (red dot seen in my video). However, if the knob over-rotate, the red dot will not be able to tell me that the position is wrong. Thus I designed this knob clip will allow me to easily see and fine adjust it when needed. After leveling the print bed, I will clip it at the 6 o'clock position for the front 2 knob and 12 o'clock position in the back 2 knobs. Not sure whether by keeping the clip at the same position will make the bed level at all times. Will report back later when I tried it out.
