I got some feedback on my Parametric Tripod Mod for a Flashlight pointing out that the head of the threaded insert doesn't have any ¼"-20 threading where the allen wrench fits in. As a result, some tripod mounts may not thread into the insert properly.
I solved this by inverting the ¼"-20 threaded insert. In this model, it inserts from the top of the model and screws down to sit flush with the bottom of the model. The ¼"-20 threading goes all way to the bottom of the insert, which means it engages the tripod's threads much sooner.
After printing, I used a ¼"-20 threaded insert to mount atop one of my tripods. At most angles, my small focusable LED flashlight fits well and a rubber band holds it snugly upside down.
The base of flashlight I'm using measures about 70mm long with a diameter of 27mm. The included STL file (Flashlight Tripod Mount -- Inverted Insert -- 27mm x 70mm.stl) was generated using these values.
If your flashlight isn't that size, install a copy of OpenSCAD and make changes to these two variables to match your flashlight:
