Saw this from "Hector Garcia" in one of the TF 3D Printing groups on Facebook. I assume the watermark at the bottom is them too. I honestly don't know if I'll bother with the unfolded legs -- not a good look, unstable, gangly anyway -- but something that at least differentiates the robot mode a smidge more might be nice.
Also, found the SS86 Bee head I like; it's from Ambitron. (The less-clean print is from an eBay seller who's stolen the design, I think.)
I kinda want to transplant the Bumper head to my Bumper-from-Hubcap custom, and put this on the Bumper body and not have to buy an SS86 Bee. Or I guess I could just put this on the Retro Bee, whatever. It's just so good either way.
TBH if the same option were available for Retro Brawn (to give him two head options, toy and toon) I'd just drop the SS86 Brawn. The forest green is just so much nicer.
