Automatic stands for automatic return of trigger after shooting. I have designed a simple inner mechanism, that allows the user to strap some rubber bands to make the trigger come back after firing.  I also changed the tolerances slightly so it moves easier and easier to print. Also made the front hook slightly larger for bigger rubberbands.
Before gluing the cover down you can experiment with the amount of resistance by adding more rubber bands to tailor it to your fingers preferences.
