bed level thumbwheel

I wanted to replace the nuts provided with flsun by something smoother

I made this thumbwheel for M3 nut, with 5 graduation for 0.1mm, and with + and - to remind which way to rotate to go higher or lower

I tried to have the tightest possible hole to fit in a M3 nut.
Depending on PLA quality I was obliged to add -0.1 in cura for horizontal expansion.
