I was looking for something simple to design to help me learn to use 123D Design. So here's a 1/200 scale kit for Spaceship Friede from Fritz Lang's 1929 movie "Die Frau im Mond".
Printed on a Replicator 2, PLA, 0.2mm, one layer, 5% fill. Fins are just short enough to print upright. Use helper discs. Finished with two coats of Home Depot primer filler, sanding right back after each. Final paint is Tamiya hobby spray paint for plastics.
