Cooler Lid Stopper

I've always hated the way that when you put your cooler away after camping, somehow the lid always gets closed and then you can get the musty cooler smell requiring some heavy cleaning the next time you pull it out.

This is just a simple little thing to prevent the cooler lid from being able to be closed while its stored for the off season. the width of the cooler lip is a parameter. I have included the fusion 360 and the step files with the stl. the width is currently set to 31 mm which fits my coolers.
