V5 fire test (reliable with up to 10 bands, let me know if you can do more!):

Too complex? Bed too small? Made this 6 shooter that's wayyy easier: https://www.thingiverse.com/thing:4753071

UPDATES
V6 - Fixed firing reliability issues across the board. Made assembly easier, bands don't need convoluted mounting any more. Made the design easier to print. Dozens of small tweaks... this may be the final version, we'll see after I make 2 and test.
V5 - Display Stand, nubs on top to keep the bands a bit separated so they don't pinch the release catch, fatter release for wider bands, magazine tapered and smoothed at the corners to help with band release
V4.1 - Small bed version added (front and back pieces)
V4 - Less tweaking needed to get full auto working, smoother operation, left and right hand versions, NOTE, Elastic release may be updated shortly, trying to get the full auto to be more reliable so changing the angles a lot.
V3 - Complete overhaul of internals after testing, way more reliable now
V2 - Shoe mechanism changed for rocker, doesn't 'mag dump' or double fire in full auto now.

This works by loading bands onto a rear rotating square magazine which is kept from rotating forwards by a rocker. Note: Load the magazine with the bolt locked forward to prevent it from hitting the rocker.

When you release the bolt it will cycle backwards knocking a bulge on the rear of the elastic catch into the rocker causing it to rotate a quarter turn. This will load a band onto the catch, which is then held in place by the bolt getting stopped by the trigger sear. When you pull the trigger, the band on the catch pulls the bolt forward and releases the band towards your target, then another small band on the bottom of the catch pulls the bolt back and the catch hits a shoe again allowing the magazine to rotate another quarter turn. This repeats with a satisfying noise, the bolt cycling back and forth like a real open bolt SMG, and lots of rubber flying towards your intended victim, and good fun is had by all hopefully.

Holds 8 rounds one at a time or 1 15 if your really feeling lucky (V4 made this much more feasible). I MAY try a hex version that will increase capacity by 50% in V6.

V5 Non 3D printed parts list:

Non-3D Printed Parts
4 - 19mm 1/8in rods for hammer/rocker/magazine/trigger
1 - M3 nut for grip
1 - M3X16 cap screw for grip
3 - M3X12mm cap screws for frame
3 - M3X4~6mm cap screws for handle
3 - Size 16 rubber band to tension hammer (goes around hammer and band catch, give it a few turns)
1 - Small loom size band to tension trigger

Updates:
V5(ongoing) - More realistic trigger design
V4 - Magazine improved strength (thx to soelvberg for feedback), added stand, lots of little tweaks. Magazine now needs gluing so you can change the colors, doesn't affect servicing.
V3 - Trigger and Magazine now only need one spacer (before they needed 2 but now one is already attached, the reason for this is to print without support)

Fully functional 6 shooter Rubber band gun. Hammer cocks and action works, hammer hits a block to release a band, just like the real thing! So close to scale you can fit real grips on it!

Comes with 3 interchangeable barrel sizes. Each barrel type comes with 2 options: Screw attachable orange plug (child proof), or slide on orange plug. These may or may not be required in your area or for kids safety. But I'm giving you as many options as possible :)

Full disassembly for service, just needs M3 screws, NO gluing required! ...ok, you have to glue the cylinders on but that's only so you can change their color.

You will need cheap 1/4 welding/soft steel/brass rod for the pins comes with pin sizer, just put the rod in the sizer and cut on the line for a perfect fit!
