TFA Grimlock Bicep Swivels

thingiverse

A basic recreation of Animated Grimlock's black legs, now with a cut to allow for bicep rotation. It's also usable in dino mode but it's not very practical so i didn't photograph it. Note that the pieces aren't perfectly symmetrical so you'll have to mirror them. Depending on your printer and plastic choice you might also need to slightly thicken the peg with some superglue or floor polish.
