The trigger lock I made allows to lock the trigger of the rifle as per the requirements for keeping and transport weapons. For locking you can use a simple suitcase small padlock, as I use, or you can use any padlock that fits.

No support needed. You can print it with PLA, PETG, ABS (ABS recommended).

The devices were printed with GD Filament materials.

Printed on Bambu Lab X1 Carbon, layer height 0.16, printing time 17 minutes.
