My wave belt pouch just wasn't what I wanted. Velcro is nice and all but I was remembering this Russian Makarov efa-2 holster I saw some years ago. Personally I would never use a slide through design like that for a handgun but it sparked an idea for a tool holster. Failures are not posted here because I never photographed them however I settled on a less elaborate design.
This may not work for all materials but it feels dreamlike in nylon. The inner springs soften up over time as they absorb atmospheric moisture however the whole design expands to compensate a bit and grips harder. A revised design will rotate the belt clip 90 or even top down as I am very confident that the tool will not slip out on its own.
4 holes are for m3x12 bolts, this was designed for nylon and epoxy so don't expect those to support it all. The design is extra thick because of nylons flexibility, printed at 30% infill and any more would cause extreme warping and failure.
