Trade, My 3D printed safe lock for ???
it was printed in a large commercial machine not a smaller home machine. the dial spins and it works.
as for value it would cost about $300 (6hr build at $50-60 a hour) to have one printed at any of the 2 shops near me that do 3D printing for the public.
any reasonable (almost all) offers will be considered.
you can find more info here http://www.thingiverse.com/thing:2047 I did not design this. I only hit print on the printer and cleaned it, all credit go's to the designer.
