• Keychain

Since the key needs to be turned two full rotations when opening the door, and my keychain is loaded with various items that make it difficult to rotate smoothly, I designed this key spinner equipped with bearings for effortless, fluid rotation. The bearings were leftover from my RC car hobby—just go ahead and purchase them based on that specification.
