Anycubic i3 MEGA Bed Levelling Knobs With Labels

I just wanted to share the successful bed knob handles I designed, It has 8 segments so each segment is roughly 45*
Wedges works for locking the bed after finishing adjusting the knobs, place one in as near as the segment hole where knob naturally loosen for turning . For example in my device clockwise motion loosen the knobs so wedge pushes back locks the bed.
