The original design was great, IS great, but over time when printed in petg the sides start to warp apart. They also catch on things at the worst times possible.
SO. I've remixed the design to tighten up the belt loop just a touch, and add a cross-brace to stiffen up the holster in general.
Print upright in PETG, with 4 perimeters top bottom and sides, for an almost competely solid result.
The author remixed this model.
cross-bracing added to stiffen up the holster as a whole.
