3L Pot Fluxring Cover

Bottom fluxring cover for a [3L Jetboil pot](https://www.amazon.com/Jetboil-Ccp300-Cooking-Pot-3-liter/dp/B004Y4QB9M/ref=as_li_ss_tl?ie=UTF8&linkCode=sl1&tag=whirligh03-20&linkId=cb2501a1f056f09a02e9e6eea7a56c8b)*. It's designed to replace a [previous version](http://www.thingiverse.com/thing:453688) which melted when I forgot to take it off before using the pot.
