While you can put the electronics into any kind of glove, there is nothing like a nice looking 3D printed part to finish a project. So here is how we did it with a focus on getting a really nice paint job on the external parts.
There are a few models out there that are available for download, so we won't get to far into that part. Here are a few examples we found:
The important part is that you leave enough room to fit all of the electronics into the glove.
If you make a full gauntlet, it will be easy to store things like the battery, but it may be easier to stash the bulk of the electronics inside the glove itself to reduce the number of wires which could break.
Primer/filler was used on the parts to get a nice, smooth finish. This takes time and a lot of delicate sanding.
Sand the 3D printed parts to knock down most of the ridges.
Apply two coats of the primer/filler with a light sanding between coats.
It takes a lot of time, but the results are incredible. No one would ever guess you 3D printed any of it.
Once you get things rather smooth, apply a generous coat of black spray paint formulated for plastics.
Let that completely dry, then wet sand it until the parts have a dull and smooth appearance.
Now you can add weathering because nothing looks new and shiny for long.
Lastly, cover the parts with a protective spray to lock in that glossy look you are going for.
