K'nex Marble Shooter

I made a semi automatic marble shooter that I wanted to share. It has a capacity of about 16 marbles.

Step 1: Base

The first step is fairly simple.

Step 2: Main Body

This is where it gets confusing.

Step 3: Firing Mechanism

This part is also simple.

Step 4: Extras

This is a stand which I find pretty useful.

Step 5: Final Product

It's finally finished. When firing try to not pull for too long as it might result in marbles spilling out.
