Simple Semi-automatic Rubber Band Gun

Small, accurate and fun toy semi-automatic gun that shoots rubber bands. Includes small targets to compete.

Prerequisites

• Contact glue to attach the body parts.
• Rubber bands about 25mm long and 1.6mm in diameter like these.
• One orthodontic rubber band like this. It is not mandatory, you will only need it if you want your trigger to return when you do not have any rubber band loaded.

Features

• 5 fully semi-automatic shots, easy to reload.
• Ergonomic design, inspired by Glock 42, easy to shoot and aim.
• The body of the gun is available in two different sizes, the difference is ±3cm in the length of the barrel, the other parts are compatible.
• The magazine can be removed and put on, it fits with a click, store ~6 extra rubber bands in the magazine.
• Includes small targets to practice your aim and compete.

Printing

• 2 body parts, there are two sizes available, make sure they are both the same size.
• 1 trigger.
• At least one magazine.
• Print if you want a few targets, print them multicolor to make them look better.
• PLA works nice, it does not require special materials or supports.

Assembly

• Insert the trigger on the left part of the body.
• Now put your orthodontic elastic band, check the images to know where, this step is optional and does not affect the operation of the gun.
• Carefully apply the contact glue on the left part of the body, check the red shaded image to know which areas to glue, make sure you don't glue the trigger to the body, the outer areas of the gun are the most important, especially the top and those around the trigger and magazine.
• Now fit the right part of the body on the left part and wait for it to dry, the ideal is to add some weight on the weapon so that it sticks completely.
• Once it has dried, you will be able to fit your magazine and load the weapon with rubber bands, ready to shoot!
