Robwzor's GlowaSmoka dragon head sculpt has the amazing property of looking good no matter what you do to its proportions. I give you... FonaSmoka, dragon-head iPhone 5 case. It doesn't fit well in most pockets, but it does fine in a ladies' purse. Amazingly ergonomic, it feels great in one's hand, makes it easier to hold the phone when taking photos, and acts as a stand both laying down and standing up.
I must also mention Brandonw6's iPhone 5 case as a source, but Thingiverse is not letting me add it to the sources section:
The buttons are very fragile - don't push them if the phone's not in the case! Once the phone is inside, they're fine.
Printed in FormFutura's wonderful EasyWood™ Ebony at 225ºC using the Z-Temp™ temperature controller.
Dry-brushed with "African Gold" Gilder's Paste and "Antique Gold" Rub n Buff wax finishes. Didn't bother clear-coating it, and the finish is mostly still there after months of daily use.
