I printed out a tiny version of the clock on Thingiverse -http://www.thingiverse.com/thing:17144 . Unfortunately, after a few ticks it would stop ticking as the pendulum swung lower. Too much friction I guess despite the lithium grease I used. But it looked cool. Made with a 0.10 mm http://www.jerrill.com nozzle . Didn’t go smaller because of the detail on the escapement wheel, but the gears could definitely be made smaller if I kept the escapement wheel larger.
