Sonex Fuel drip catcher

This is a liner for the sonex fuel filler neck. It is intended to prevent minor misfuelings from letting gas get into the cockpit. However, it has not yet been tested in a flying aircraft and you should assume it won't work. No warranty is provided. ;-)

If you print this I'd appreciate a paypal $20 donation, which I'm sure is small compared to the savings in effort compared to making something in aluminum. I recommend printing in TPU plastic.
