About this 3D model

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://hpclaser.co.uk/index.php?main_page=product_info&products_id=40 so I would imagine it fits most, if not all machines of this type.
