This is a printable replica of the holsters that held the “Boomerang” Phasers in DS9, VOY, and the TNG films. It should snugly fit most phasers, but some modification might be required. I experimented with a printable Kydex pattern, the type of material used to make these holsters in the production, and I think it did alright. However, I've also been informed that the Cura “fuzzy skin” feature does a damn good job too, so I've included two versions.
"holster_custom_kydex.stl" features the Kydex pattern and is the one featured in my photos. This one required some significant modification to get it to fit my phaser. “holster_custom_new.stl” is a newer version without the Kydex pattern, but has a much wider nose and is much easier to slot the phaser in-and-out of. Both should hold a phaser snugly as long as you put some fabric inside to hold it in place, which was also something done by the production.
