Here there are some squids designed in openscad
there are various version of eye positioning and in each you can choose the number of legs and add or remove the keychain handle!
Inspired by Nush's squid: http://nush.it/peluches/squid that is awesome!
Instructionsprinted in PLA
I printed these at the default dimensions, but also bigger they are nice
you may resize it smaller (like half) to get a keychain out of it!
enjoy!
