This is a work in progress. Not all tracks have been done yet.
Will be done soon though. Here is (NOT YET) all the F1 tracks as nicely sized keychains that will fit well on your keys or bag, or whatever you like to put keychains on. They are quick and easy to print, with them taking 30-50 mins to print. They are all about 6 cm long and are quite sturdy, so they wont break or anything. A normal keyring will fit on them, just make sure it isn't too thick (hole for keyring is 2.5mm).
Examples shown are Melbourne and Brazil
