I couldn't find a model for a lightsaber wall mount that wasn't bulky and super visible, and I noticed my lightsaber (Sabertrio Aeryn) had a Covertec wheel, so I figured I'd leverage that to make a little wall mount. Just attaches with a standard small drywall anchor and screw.
It does need an attachment at the top however to keep the top part from tipping over. I use a clear “snap in” holder from Amazon but there's surely many 3D printable options.
