I have done a little bit of 3D printing and it is very cheap as the prices have come down so much as basic decent 3D printer starts at around $3k like the makerbot which prints layers of ABS plastic melting the plastic from a spool into a shape.
great that the guy isn't trying to get rich off people
Ben Heck and Jpop also use one to pro to type and trial different post designs etc so allows developing fast on the day not draw up, send away and wait 1-4 weeks for someone to make and then doesn't fit.
I have wanted one for a while.....
