This design was inspired by the mechanism used in EJTH's Rubber Band Gun MKII although this model is an original design and probably wouldn't be considered a remix.
The uploaded .3MF file has the eight parts needed to print one complete gun. They are joined with CA glue and - bang! You have five shots of semi-automatic rubber-bandery.
The gun was designed to use some #18 rubber bands that I had, but I've uploaded the Fusion 360 file as well so you can alter the ‘barrel’ length (see User Parameters) for whatever you have lying around.
Assembly Instructions:
- Place the slider on the 'barrel' of the gun, in the orientation as seen in the photos above.
- Add a bit of CA glue on the two areas where the grip frame mates with the barrel body, make sure that CA glue doesn't get into the slider. Press the barrel and grip frame together, ensuring that the slider remains in its track.
- Place the trigger button through the cutout of in the grip frame, noting how it fits into the slider. This part is tricky - put a bit of CA glue where the trigger meets the prongs on the slider, and press the trigger into place. It will only need to seat a few mm in.
- Ensure the mechanism slides back and fourth.
- Slide the printed spring into the cutout in the grip frame, applying some CA glue. The upper portion of the spring should push the trigger forward.
- Push the trigger guard into place.
- Attach both grip covers to the grip frame with CA glue.
The .3MF file is setup for PLA printing on my Prusa MK3s, adjust as necessary for your setup. Supports are needed in two small places, on a protrusion from the barrel and in the hole for the trigger on the grip frame. All other print settings as standard, you may want to turn on ironing for aesthetic effect.
