This will work for the X. It should also work on the 8 and Andriod phones but I have not tested them yet.
Modifications for remix
Wider to allow for case
Textured for better look
Extra room in electronics bay
Buy a compatible charger (see below)
Print the dock and cover parts
Disassemble the charger and put the PCB and coil into the dock case, fastening the coil with double-sided tape or hot glue. You will probably need to extend the coil wires.
Attach the cover parts mine snapped right in but some double-sided tape or glue might be needed.
