Nebo CSI flashlight holder is perfect for a Buzz Pro (or likely for a Provari or similar).
For VVG I found a small cell phone pouch holder that is quite nice, but I need to attach a belt loop snap properly. Right now I have a snap attached to the standard belt clip on the back of it, which messes up center of gravity. Someone who does heavy sewing (shoe repair) would likely take all of 2 minutes to sew a loop holding the swivel near the top of the case.
