car slingshot

Its a fun slingshot for cars and other things. We tested various other stuff.You just need a rubber and 2x M4 screws or 2x M3 screws and 2x M3 inserts.With 2 rubbers a car can move pretty far, usually we just use 1 rubber.From the base-folder all 3 parts are needed.The extension-folder is optional.From the end-folder one of the baseparts is needed and the top is optional.The link is a bit loosy, so its easier for a kid to assemble it or change parts.My printsettings:0.6mm nozzle70% infill0.95 mm line width0.2mm line height Have fun :)
