Airsoft Spring Pistol

Hi,

I wanted to create a Pistol with a strong spring almost 100% 3D printed. The design of the pistol is strong based on Beretta. I am very happy with the result, even if it needs a bit of work afterwards to get it working.

The working principle, as any Spring powered pistol, is using the energy of the spring to push the air into the barrel. For that I used a 1,5x14x100 mm Spring and a Nail to hold the trigger rotation. Careful with this strong spring!! maybe consider using 1 mm instead.

For the cylinder there are 2 options, you can print "PISTOL-Air_Cylinder.stl" and sand it a little bit from the inside. Or you can use a 1x20x88 mm Aluminium barrel for extra efficiency, for that use the "PISTOL-Air_Add-Alu_Cyli.stl" adapter. Both work fine, but with the printed one you will need more lubrication.

For the Piston-head there are also 2 options. You can use "P-Piston_Head_v0" with a strip of kitchen sponge. It works amazing when achieving the right pressure against the cylind
