Airsoft 40mm Grenade Launcher Repair

thingiverse

I am replacing the stopping tooth on my launcher, which is designed to lock the slide and prevent it from falling off the front of the gun. Unfortunately, mine broke, so I'm ordering an exact replacement part. The good news is that this component can be 3D printed and will function for a short period if made with ABS or similar materials. However, I opted to CNC machine my stopping tooth instead, as it provides a more durable solution. Alternatively, you could cast the part from resin. One potential issue with 3D printing this component is that the layer lines can begin to delaminate under the stress of being used in game, which may compromise its performance.
