Simple lateral flashlight holder for picatinny rail. This mount allows the user to turn on/off the light using the index finger without need of a special torch switch. 

In the picture was mounted a 25 mm diameter torch on an airsoft replica of the beretta 92 from HFC, but is also possible to mount it on different replica if they have a picatinny rail and also torch with a diameter 20-25 mm. 

Print settings for Ender-3 S1 pro: PLA generic filament, 15% infill, preheat 

Mounting: use 6 M4 x 23 mm bolts and screw the pieces together (no need for screw insert).
