NEMA 17 1:48 hypocycloid test

thingiverse

First test (printed and "working") of my hypocycloid gearbox generator (scad file at http://www.thingiverse.com/thing:481167). Pics will follow when I get my camera back! This version needs improvements to avoid jerky output motion. Perhaps changing parameters in scad file (peg diameter, etc). Still interesting test that proved it worked! Note - the linked-to scad file isn't exactly neat and tidy! Sorry!! (still learning) Instructions requires: 2x 10 mm ID / 15 mm OD bearings. 4 mm high 2x 6 mm ID / 19 mm OD bearings. 6 mm high. 1x ~70 mm M6 threaded shaft. 4x 30 mm M3 cap screws. 4 (to 6)x 10-15 mm M3 cap screws and nuts. 6x M6 nuts 4x self tapping screws.
