My son (he's 6) wanted to be Freddy Krueger for Halloween so I modeled a glove for his hand. I thought it came out great so I figured I'd share it. The fingers segments print together with a working hinge and are riveted to the back hand plate (not sure what to call it). The blades snap into each finger then are glued in place. I also used a 3Doodler to weld the blades to the finger for a more accurate look.
This is far from perfect but worked well and was a very fun project. I would assume you could scale this to fit an adult hand though I haven't tried.
Fingers were printed vertically with supports (from base only).
