There was a series of hologram-based toys in the 80s, Supernaturals; 4 minion great 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 bad-guy sword. One is lost by anyone, want to print a new one? There's a plastic or a paint that can help with that aspect, although I can not do anything about it shining.
Never quite got the blade right - I can not figure out how to pocket it because lots of energetic dimensions at once as it gets close to the tip (I am pocketing down a block from either side and the bottom), but it's close enough for a practice model that nobody asked.
