This is my second entry for Oneplus One and Ultimaker contest. It's a case with dual layer first layer are a bit flexible, and second layer is the hard one (for locking the case too). It should make your Oneplus One more protective. (not water proof case - would love to create one but there's no time anymore i think :P )OBJ, FBX, STL and native MAX are included with high subdivision and lower subdivision too for anyone that need it.Give it a try.. :)
