I designed up these self-latching hinges to fit the 5.75mm plywood of the Replicator and accept similar thickness doors or, using the inserts, to accept 3mm (~1/8" Acrylic) doors.

Printed using 0.2mm layer, 20% fill, 100C build plate temp.

Leveled the build plate with my leveling jig http://www.thingiverse.com/thing:23257 after the build plate has heated. Careful, hot things are - well, umm, hot and can burn!

The hinge pins are sized to be a press fit into one half of the hinge and a free fit in the other half. That's a quarter milimeter difference! Yeah Makerbot!

I put everything for 2 doors in one print. If you have trouble with the pins I put up a separate file for them in case you need to reprint them.
