Piaggio CIAO fuel tank cap

thingiverse

I lost my tank cap for my piaggio CIAO, so I printed one with the material TPU. No support needed. This will work for an inside diameter of max 36mm down to 32mm for the big one, and 30mm for the smaller one. The only issue I had was that TPU dissolves in gasoline a little bit, and it swells. That's why I made another version with a smaller end, so that it fits even if it's swollen. I tried also PLA, and it works! It doesn't swell, but could pop out while driving.
