Use "beefcake" version.
Tried my hand at designing mount to put this on quadcopter. Printed one from thing repository, but it didn't have enough angle and seemed to interfere with the rather easy to press buttons. Lightweight skin is probably too thin to offer much protection, used approximately same thickness as OEM hard mount. If mount is a little too loose, consider scaling ~98%.
**Friend said original design was too flimsy. Added "beefcake" editions.
This design is great... especially the beefcake variations ;-) Using a TPU with a 95A shore hardness or more will take quite a pounding. I was afraid that the Firefly micro was fragile and having a one pound quad smash it into a tree or the ground at 50 MPH might destroy it as it did my Ekon. This seems quite protective.
