Function x mobile phone is very weird in design and looks, not so attractive looking to me and i am sure its same for many as well, kinda look lot like a military grade mobile phones, any ways just try to improve the design because many don't like ugly mobile phones
BOB Hardware Design Is Open Source
Upon the release of BOB, all of its hardware design rendering files will be made available for more hands-on users to be able to download, modify and 3D print the parts to make their own BOB modifications. We hope to see a thriving BOB MOD community where BOB MOD enthusiasts will create new parts to exchange, trade or even sell their design creations.
