My nephew really likes dinosaurs, so for his upcoming birthday I remixed him a dino-shaped piggybank... I sliced it in three so it fits on my Kossel bed (200mm), just used plastic glue for putting it together. Thanks to faulty for pointing me to the original source: ErikHK's dinosaur - I hollowed it out and added the top slot as well as the breakable hole at the bottom. Can be printed in one piece, without supports. For printing on a Kossel 170mm bed, resize to 85%. No supports needed. Walls are about 1.5mm wide.
