Solution: Supernaturals Hero Minion Sword (1980s)

thingiverse

In the 80s, hologram-based toys called Supernaturals became super popular. They came in two teams: four good guys and four bad guys. Each toy had a translucent shell with a holographic sticker on it. A rubber cloak was draped over the shell, with two hands sticking out of the cloak. All of them were armed with a glowing sword. Here's a picture of the good-guy sword. If you've lost one, feel free to print a new one! I can't control the glow, but you might be able to find a plastic or paint that helps tone it down. You can use it as a keychain if you like, shrink it down for Lego creations, or get really creative with it. This was my first try at using the helix tool to design the grip; there are definitely ways to improve it.
