MR2 Vapor Canistor Closeout Clamp

This model is used to clamp closed a vapor canister lid which was cut off previously to replace the charcoal. Specifically designed around Toyota part number 77740-17020, but may work for other models with the same diameter.

You can either epoxy the bottom ring to the canister, or leave it loose and hold it with your hand while tightening the top ring. 

This makes it so the vapor canister becomes user serviceable, should you need to do so in the future.

Print this with a high temperature filament. I used PAHT-CF, though PET-CF or any other high temp filament will work. The top ring is scaled up by 1% by default to allow for a nicer fitment.

The chamfered side of the bottom ring faces down when assembled.
