This is a Star Wars inspired wrist launcher that I made and It's the first project I've put on the internet. Currently I'm trying to make a functional one that actually fires a small rocket but I thought I would make something purely asthetic to see how it might look.  The gauntlet is modeled around my arm so you may need to scale it in order to make it fit. The fit is pretty loose since my hand has to slide into the gauntlet but that can be fixed with some rubber bands being glued to the the top of the inner segment. You could also line up a glove and glue that to the interior portion (for reference, the guard should go up to the knuckle of your middle finger). The gauntlet does print with no supports and it should be oriented properly in the model (the back of the gauntlet should be on the build plate). Unfortunately I'm still tuning my printer after some mods so there are a few artifacts in my print which you'll see in the photos, but it did print as intended.
