Leonardo da Vinci inspired bicycle ==================== Wikipedia (GER) is quite sure, that the bicycle drawing is not from Leonardo da Vinci; https://de.wikipedia.org/wiki/Angebliche_Fahrradzeichnung_Leonardo_da_Vincis nevertheless I like it and I decided to design a 3D model in Fusion 360 - here is the result; some details vary from the "original" to make them 3D-printable; wheels, gears and pedals are moveable; the "chain" is printed with flexible material (TPU) - you should print it first and hang it into the frame while printing, otherwise you will have to cut and glue it to join the assembly; the rear gear is glued to the wheel with space inbetween; use a screw to guide it; the pedals are also glued to the screw and nut; BOM ------ - 2x M3x20 zylinder head screw - 1x M3x22 zylinder head screw (I cut down a M3x25) - 3x M3 self locking nut - 1x piece of 1.75mm filament to mount the handles - super glue happy printing!
