Full-auto, rapid-fire rubber band minigun with 20 round magazine the runs on AAA batteries and shoots very reliably.
Mostly snap-fit assembly. Extra parts needed only for full-auto feature. No extra parts or hardware needed for manual operation however I recommend using bearings for mounting the shaft. You could probably print bushings instead if you don't have bearings. Assembly video: https://www.youtube.com/watch?v=kMZFFGzZBas&t=12s
