Standalone Wireless Touch ID module

Building on the excellent work by SnazzyLabs and Jamie's efforts to box up the guts of an Apple Magic Keyboard for the Touch ID sensor, I present my take.

Notably, I wanted it to be wireless so I lengthened the box to fit the battery. From there I added a few other touches:

I added very small supports for the plastic weld pins. These are integrated into the model - you should print this without any additional supports. They easily break away from the pins after printing. 

I reduced the size of the screw holes on the logic board standoffs to allow me to drill and screw directly into them as I was too impatient to wait for Amazon to ship my M2 heat-set inserts. I added the option in the 3mf file to change the size of the holes to support different insert sizes - no CAD needed.

I enclosed the button frame and added a shadow line around the box. I just think it looks better this way. The overall assembly is similar to Jamie's model.

Overall assembly is similar as well:

Install and secure the lightning port

Install logic board and connect sensor, lightning, and battery cables

Fold battery over and settle into frame. Note it will put pressure on the cable to bend it out of plane. This is OK as there are additional folds on the cable to handle this.

Install the back sprint onto the touch sensor and insert it into the button tray.

Carefully latch the lid. The tabs are likely to break especially in PLA if you force it. I recommend starting on one end, get both in, and then work the other end.
