Has anyone attempted to make a Picard S3 Phaser holster?

I'll be attending my first con soon, dressed as Capt. Liam Shaw, and while I have a resin phaser (working on a full build with working lights/sound), I don't have a holster. It seems the one they made is pretty low-key, but I'm still working on my CAD skills and likely won't be able to design/print it in time. Wondering if anyone has seen a model floating about?
