Not my work at all. These are designed by 3DPrintGuy: http://www.3dprintguy.co/ and made available for free on the Rick & Morty facebook page.

The only modification that I've made is that I used 123D Design to rotate the models 90 degrees.

Legs are very thin so print with high infill and be careful when removing supports. You may want to print it bigger if you want it less fragile.

0.2mm, supports and 50% infill did the trick for me. First try at 0.3mm and 10% infall was to fragile and broke when removing supports.

Later I scaled the models to 150% and printed (white prints) with 0.2mm and 30% infill and it turned out great and much less fragile than the unscaled versions (yellow prints).
