Z Axis height Adjustment for LS3020 Laser Cutter

Just as title really! A handy wheel used for adjusting the height of the table externally. Mine came with a small aluminium knob that fits on the inside, but its a pain to easily adjust.
This fits on the M10 studding under the machine, and is pretty much the same size as the A4 working area! (You can see where I missed a bit :p)
Really simple mod, and much much easier to adjust the bed height!
Sticks out about 5-6mm out from front of machine.

Mine was purchased from HPC Laser http://hpclas
