Chainsaw fuel tank cap

Has it ever happened to you that the fuel cap for your chainsaw breaks when you try to open it for refueling? No? Well, it happened to my father, so I made this. Designed to match the threading and all-around design of the original cap for the fuel tank on a Jonsered chainsaw (from the late '90s, but I think they're still being made) but also be easier to open by hand instead of using a tool that might break it.

Incidentally, after a few uses, this one broke too - so you may want to keep an eye on it as you use it. The choice of plastic might make a difference, as it will be in contact with the fuel which probably weakens it over time. A more resistant filament than the PLA I had at home might make it much better. Still, use at your own risk. You have been warned.
