All parts have to be mirrored to fit correctly on the buildplate. Printed all parts on my Ultimaker original, layer height 0.15mm, top/bottom/wall 0.8 mm, speed 70 mm/s, flow 110%, fill 20%. Adapted the movable engine from http://www.thingiverse.com/thing:50988 to a 4 cylinder engine. used gears http://www.thingiverse.com/thing:6544 scaled to the project. got a solar powered motor from www.conrad.nl Instructions after print, carfully sand all parts before fitting them together with superglue. make sure the crank-shaft has enough play to run smooth. engine is a solar powerd motor with a diameter of 24 mm, 0.5V
