Seriously, that would sell. Or a lightsaber. The Venn diagram of "3d printer owners" and "ST/SW fans" would be 2 circles drawn nearly on top of each other. Charge $15 for the d/l. You'd overheat a T1 line

And I thought I was having a wacky idea. Actually, I'd probably be too paranoid about medical issues to touch that. The story that will inevitably ensue when a group of 11 year old boys start printing whale penises and taking them to school to frighten the girls with would be hilarious though

I would start off small. A warp core maybe out of reach for most.
How about a Flux Capacitor?
Oh look, the plans have already been made
