This is a sort of working grab pack that has been tested and works but with no firing mechanism. What you do is tape a piece of string to the rollers and then you roll as much string as you want. It is recommended to use sewing string for easy use. After that you thread string through the hole and then put the roller in. After that you thread the string through the cannon and then you tape the end of the string to the dummy stand bulb and put the bulb to the hand. 

 Any filament works for this though this is in beta so I do not have any instructions yet.

 You will want settings set to 0.2 mm layer height always and 30% infill. You will also have to activate supports which are recommended to use original supports for easy removal.
