spring caps gun

thingiverse

Right and left sides, as well as the trigger, have been modified/improved to use a spring instead of an elastic band and a more solid axle for the trigger. The 5mm x 15mm axle is used for the trigger, while the 4mm x 18mm axle is used to hold the spring in place. The extension spring has a maximum diameter of 7 mm. There are multiple positions available for securing the spring. It can still function with an elastic band if you don't have a spring. All other parts and information can be found on the original model's page.
