5 round automatic rubber band gun using micro servo

thingiverse

It's designed for educational robots using micro:bit with a servo motor drive unit that provides 36-degree rotation per single release. The sixth notch doesn't function properly. The models of Bracket and Barrel have been revised to minimize jamming caused by individual differences in the shape of servo horns. If setting the rubber band at the first notch is challenging, the servo motor should be secured to the screw holes on the outer side of the bracket, and the barrel's position adjusted lower to prevent contact with the rotating plate.
