The inside of cupboard doors mostly is wasted space, so why not use it to store your pan lids. That way you can stack your pans from large to small and keep the lids on the inside of your cupboard door, ready for grabs.
The design is made in OpenSCAD so it can be parametric, which means you can easily modify the numbers to fit the lid from your pan. Or even use it to do something completely different (plz, let me know).
BTW, this is the reason that i love 3D printing. These things are not for sale, but if you can imagine them, you can design it and print it. Often the same evening. And maybe this helps my wife see the value of these techy toys of mine ;)
The design is inspired by this guy who used adhesive hooks to do the same (http://www.instructables.com/id/Easiest-Cupboard-Pan-Lid-Organiser/)
And there is a story in dutch about these clips on my website (http://www.oiepoie.nl/2015/05/26/pannendekselhouder-uit-de-3d-printer/)
