To have a save launch we designed and developed the "X8-catapult". The normal length is 2 meters. Its possible to use an additional 1m-extension part, for an softer and more powerful launch!
To save money and have a little bit better feeling, doing something for the natural envirement, we developed the Granulat-Extruder/Hotend GEH 1.0. So you can use the much cheaper granulat instead of filament.
