My kids love the octopus, and kept asking for a starfish. This did the trick! I drew this in sketchup freehand. It took quite some time to get the surface right. Looks very topographic once printed. A great flat bottomed animal for the Makerbot. Perhaps a flounder is next up :)
Update: This prints really well if you scale it up as well, I've printed it so that it just fits on the build platform, takes a bit longer, but comes out great. Sort of neat that the ends of the feet tend to curl up a little due to the heating/cooling of the plastic.
Was very odd but overnight these things crawled up on a few rocks I'd left on the table...
Update 10/15/2011: if your original needs a companion, check out Squiggly version.
