This is a 100% fully 3D printed matchstick / toothpick shooter with a quickly and easily operated loading system, capable of firing 1 projectile per second!

Also, I know what you might be thinking: Can I add a piece of sand paper in the magazine so that the match ignites when it is shot out of the gun? Well, I couldn't get it to work, but you might!

This gun also works with pretty much any projectile that you can fit in the holes of the magazine, even small pen springs!

No rafts or supports are needed.

Assembly:
First put together the two halves of the inner shaft and then put the ends of the grip onto the grip. The two pictures in the end can help. Using glue is recommended, but the gun should function without.
Then, place the parts into the hull according to the image.
Then, slide the other part of the hull on. You can glue this part in place, if you don't feel like keeping it in place with your hand. (If this part doesn't want to go in, you can try pushing the springs in a bit.)

Shooting:
To load the magazine, put the projectiles in it, 1 match/toothpick in each hole. To load the magazine in, load the gun by pulling the grip back so that the pin goes over the hull wall, arming the gun. Then, slide the magazine in. Make sure it goes in the right way.
To fire, push the pin in the back end of the hull to the side.
To reload, arm the gun by pulling the grip back so that the pin goes over the hull wall, and then push the magazine down so that it snaps into the next position.
In case the shaft keeps getting stuck: The easiest way would be to cut the ends of the matches/toothpicks and flattening the ends. (in width.) But the most reliable way would be to use thicker matches/toothpicks.
