Sizes Provided are from hole centres at extremes for calculating pivots, not length of the linkages. Each link is actually 1cm larger than described length.

THE FIRST 6 Sizes from 2.5 - 8.5 do not have their decimal places displayed, I apologise, I have not printed these yet

FIXED 25-11-15

3/16 inch screws threaded the holes very nicely for me, just twisted them straight in. Otherwise 3mm filament will suffice for connections.

Sizes are shown on relevant stl files, from 3cm to 19.5cm in 0.5cm increments. Do not feel obligated to use the exact cm's remember they are just ratios of units, cm's just helps when mounting it. I have a piece of wood with relevant measured and drilled holes for mounting, then just screwed straight into the plastic.
No bolts were necessary, just screws or filament (filament can be bent around for securing or melting down)

objects can be scaled on the 'z' axis for extra structural integrity. For useful ideas see some great ideas on wiki, ask a friend or teacher or search the internet.

Hope you all enjoy.

I can take request for allocating holes at different points, i.e 1/5, 1/4 for levers and dual actions.
