I built this a couple years ago from an old Schwinn 10spd. My original plan was to make the tank out of metal. The cone shapes on the end were keeping me from finishing it. I got the idea a few nights ago to 3D print a tank! I had to print it in several sections because of the limited size of my printer which is 8x8x10. What you see in the pictures is the tank still in several pieces and raw plastic. I plan to epoxy some strong magnets inside the sections and then glue them all together. The magnets will hold it onto the bike.
The orignal post on this bike. My latest creation.
