Malyan M150 Bed Level Nut - ZigZag Pattern

This is a Malyan M150 Bed Leveling knob (Zigzag Pattern) .

I made these knobs for my Malyan M150 since all the other available knobs I liked were either two big and so it would not be possible to move the bed forward completely or not too comfortable to turn.

This one is as big the knob can get on a Malyan M150 while being able to clear the front/back .

Print at 20% to 40% fill for strength.
Print four thumbwheels.

Additional hardware required:
- 4 M3 nyloc nuts (normal M3 works but bed levelling may have to be done more frequently)
- 4 M3 washers (they go between the bed and the knob)
