reloadable magnet 'web' shooter mk 2 prototype

This is a prototype of the magnet projectile web shooter I've been working on. If you plan to use this as a long term thing, and have the opportunity, get a 3.7v battery instead of aaa batteries and alter the stl to fit the 3.7v battery, as I only used the aaa battery pack as a short term power source for this prototype, and continued used will probably kill the motor I used. I used a motor I stripped from a mg996r servo, and the stl is made to fit the motor from a sg90 servo, which i want to use in the future. again, alter the cartridge to fit whatever you've got, but know I will be upgrading this version with a better suited battery, motor and more in my next version.
