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:

• flashlight_height: The measurement (in mm) from the base of the bulb to the end of the flashlight.
• flashlight_diameter: The measurement (in mm) of the flashlight handle's diameter.
