the design and build instructions are not complete! things may change. feel free to submit your ideas and improvements.
1. print all parts and smooth all inside parts! 3. buy a metal measuring tape or use an old one (e.g. https://www.amazon.de/dp/B0078E23NI/ref=cm_sw_em_r_mt_dp_U_rAivDb692EG6Q) 4. cut a 5cm part from the measuring tape.(will act as a special spring ...) 5. use the 2 trigger parts and glue them together. 6. cut the measuring tape sides to fit between the trigger and the lever. 7. glue the mesuring tape on the lever and take a m3 screw to fix the lever. (but keep it move smooth) 8. follow the picture to complete the whole snap gun:
9. the back side of the handle is adjustable if you use a m3 screw with 2 bolts you can configure the spring pressure.
Log: 15.08.19: (Blender file only) - Allow more spring pressure. - Pressure stick spring cut and fix. - snap part allowed movement wall. - deeper trigger hole impress.
