Starfish

thingiverse

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. Instructions I print these using raftless printing configured basically how they describe on the makerbot wiki (http://wiki.makerbot.com/thingomatic-doc:raftless). The modifications I made are: 1) I changed the Object First Layer Feed Rate Infill Multiplier (ratio) to be 0.5 2) I change the Object First Layer Feed Rate Permieter Multiplier (ratio) to 0.5 3) I changed the Object First Layer Flow Rate Multiplier (ratio) to 0.9 4) I disabled the Outline feature and generally delete the lines of gCode that do the warm up extrusion. These changes make the first layer go down slower and a little wider/thicker so that it adheres to the platform very well. I was noticing that the outline and warm-up extrusion generally left buggers or lines of plastic that then caused the early layers to peal off. The changes above fixed that.
