I designed this Suppressor for Airsoft with a locking mechanism so you can really have it really locks in and does not move.
The thread is also designed to fit perfectly when printed with FDM-Printers.
What you will need: 1x M3 12mm screw 1x M3 Hex nut
Instructions: Just place the hex nut into the bottom compartment and put the screw on the side. It should be pretty self explanatory.
Dimensions: Length: 220mm Diameter: 35mm
For best result outdoors I would recommend using PETG or PET Filament. I used Formfuturas ePET Filament in black.
3D Print Settings:
0.2 Layer Height. Brim Smart Layer Height should also work, but with 0.2.
