Trackpad + Touch ID using full-size keyboard parts

I really liked @atomicdude's model, but I prefer to have Touch ID on the right, so I remixed it and added some small improvements.

List of changes:

• Touch ID module moved to the right
• mounts for other components moved accordingly
• adjusted the lid and battery shelf mounting holes for the M2 heatset inserts
• slightly thicker shell to accommodate heatset inserts without artifacts present in the original model
• removed bottom holes

• added a small chamfer to the lid for easier trackpad attachment

   

Required parts:

• Touch ID button, main board with the lightning connector, and battery salvaged from the Magic Keyboard with numpad
• 8 M2 4mm heatset inserts
• 8 M2 6mm or 8mm countersunk screws 
• Various screws from the keyboard
• 2 lightning cables (Aliexpress)
• 1 USB C connector (Aliexpress)
• a bit of wire to extend cables
• rubber feet

• tape

   

Quote from original model regarding screws:

All of the screws used for the PCB/Port/Touch ID are from the Magic Keyboard.

1. For the PCB I've used the 4 grey screws;
2. For the lightning port I've used 2 black screws with a small head
3. For screwing the lightning port shell into the case I've used 2 black screws with a big head
4. For the Touch ID I've used the same screw and mechanism as in the original keyboard, 4 silver screws and 2 black screws with a big head. I've also transfered the small round metal piece used for the clicking mechanism of the Touch ID

Assembly:

1. Install heatset inserts
2. Extend lightning cables and solder them to the USB C connector
3. Attach the mounting bracket to the main board's lightning port
4. Attach Touch ID module to the top lid. Do not forget the round metal piece, and do not overtighten silver screws, or it won't click
5. Attach Touch ID ribbon cable to the main board
6. Route the touchpad charging cable under the main board and screw it in
7. Connect the main board charging cable
8. Install battery shelf
9. Attach USB C port to the case. Make sure that the latch popped back up and is holding the port in place
10. Attach the battery and secure it with some tape
11. Close the case, connect the touchpad to the charging cable, and pop it into place. This may require a little force
12. Add rubber feet to prevent it from sliding around
