Height-adjustable table legs for micro circular table saw (w/ PROXXON FBS 240/E)

Use 3 or 4 of these together with the referenced rotary tool clamp ( http://www.thingiverse.com/thing:32072 ) to make a micro table saw for PCBs or other small parts. I'm using a 44mm HSS saw blade for mini rotary tools.
An aluminum plate (ca. 4mm thick) will act as a small table.
Use 60mm countersunk head M6 bolts and make sure the head disappears completely in the plate (to do). Put an M6 nut into the slot in the part and insert the bolt. Attach to the base plate with M4 bolts or wood s
