One thing we have discovered in the RepRap project is that you don't need a
wonderfully accurate production machine to make the parts for a good working RP
machine; all you need to do is to design things rather carefully, to add a few
judiciously-placed screw-adjusters, and to be able to borrow a $30 digital
caliper for a couple of days for calibration.

Indeed, I'd say that - if you can hit about 0.25 mm reasonably reliably (we're
still going for 0.1mm though) - then mechanical strength of the produced parts
is more important than accuracy. Fortunately the polycapralactone that we're
using is as tough as old boots...
