iPad mini 2 wall mount

Made this wall mount for my iPad mini 2 to use for CCTV monitor.
4 shells, 0.2 mm layer, 10% infill.
I put 6 magnets in the back to stick to a metal sheet, 15mm X 3mm magnets used.
Cut some metal sheet about 1 mm thick then drill a hole for the cable to go through, drill some small holes and mount to the wall.
