About this model

This started out as an exercise in making the smallest ball joint tentacle that I could get to print reliably on my printer. It turned into a cute little octopus when I decided to make a fun gift out of the tentacles. It's surprisingly annoying and time-consuming to build, since each segment needs to be hand-trimmed of support and carefully snapped into the next, but the resulting toy has a lot of flexibility and posability. Printing the segments in all different colors to make a rainbow octopus is optional but highly recommended. Update 4/5 - I was experimenting with some freehand sculpting tools, and created a big-eyed alien head for the octopus that I've uploaded. Update 4/7 - added a fantasy steampunk submarine version of the main body. Update 4/9 - skull body remixed from
