UPDATE: Version 2 is available.

Using the OpenSCAD file from Jay Speidell I adjusted the holster to fit the Baton 3 Pro Max flashlight. I also added a lip to the belt clip and a cutout for the flashlights clip. 

The flashlight was slightly loose but a little crafters felt and it was just right. The felt also eliminated that scratching noise as the flashlight was inserted / removed.

I printed this in PETG with support.
