One-piece Paper Airplane Launcher

***IMPPORTED FROM THINGVERSE*** During the season the Mark Rober’s World’s Smallest Nerf Gun video came out and we wondered if a similar process could be applied to a paper airplane? ( https://youtu.be/9c2NqlUWZfo?si=hDiZxToKSbAoWZpr ). The answer is Yes! Even though we didn’t use this during the season, here is a one-piece 3D printed paper airplane launcher. It just flexes. No rubber bands required. No assembly required. It can be printed on a small 3d filament printer (180x180 mm bed), such as a Prusa MINI, and in a relatively short (2 hour 22 minute) print time (with the Input Shaper feature, which reduces the time). Included in the video is an easy-to-fold airplane, made from half a sheet of letter paper, that flies straight and consistent, and will go about 4.5 meters (much further than needed for CENTERSTAGE). The launcher was designed using OpenSCAD ( https://openscad.org/ ) and specifically designed for PETG filament, which has more flexibility and higher strength, than PLA, making for a better flexible (compliant) design. For this design, when latched: Force to pull launcher to trigger for PETG is 19.2 Newtons, for PLA is 22 N. PLA has greater potential energy (35 N-mm) than PETG (30.4 N-mm). PETG has greater margin to failure than PLA. Assuming: Modulus of Elasticity (NEWTONS PER mm^2), PLA = 2344 Modulus of Elasticity (NEWTONS PER mm^2), PETG = 2068 Print Settings Printer brand: Prusa Printer: MINI Rafts: Doesn't Matter Supports: No Resolution: 0.20 mm Infill: 15% Filament brand: Doesn't matter Filament color: Doesn't matter Filament material: PETG
