Case “Giant's Causeway” for POCO X3 NFC For the POCO X3 NFC Case, I was inspired by the natural monument - Giant's Causeway. The cover consists of: • two elements of the outer casing (printed from PLA); • two elements of the inner case (printed from TPU, Shore hardness = 75D); • four screws (printed from TPU, Shore hardness = 75D). Please do not use PLA to print the inner case and screws, it is not suitable for strength properties. Please use a coin when tightening the screws. P.S. The design of the back cover of the outer case is quite simple and you can modify it to suit your own design. P.P.S. In front of the outer case, I left another 3 mm of thread, which can be used to place decorative elements or your functionality on the threaded mount.
