There was a series of hologram-based toys in the 80s, Supernaturals; 4 minion good guys, 4 minion bad guys, they were all a translucent shell with a hologram sticker on it, a rubber cloak over the shell, two hands going off the cloak, and a glowing sword.
This is the good-guy sword. Anyone lose one, want to print a new one? I can't do anything about it glowing, but maybe there's a plastic or a paint that can help with that aspect. Use it as a keychain if you like, shrink it down for legos, go bananas. This was my first foray into using the helix tool for the grip; could have been better done.
