This is a 3d printable folding stock adapter compatible with airsoft guns.

It can be attached to any gun with a 20mm picatinny rail behind the receiver, such as MCX, or MPX.

I designed this modeling to be suitable for 3D printing and to have great durability.

• The hinge is reinforced to be optimized for 3d printing. There's an additional fixture on the hinge, so it doesn't flutter around.

• A full threaded M4 bolt is inserted into the stock to increase its durability. Buy a 500mm full threaded steel M4 bolt from a local store, screw it in place using an electric drill, and cut off the remains with whichever tool you prefer.

• The hinge axis is also reinforced with a M5 40mm headless screw. Thanks to the headless screw, the axis is durable even if it is vertically printed.

• AEG Stock tube from E&C fits the best.

• Included two types of stock holder. Print whichever you like.
