GamePi Advance Touch Case Top

It's pretty good! This is a work in progress, I intend to sell a kit with all the silly work done. For example, cutting PiGRRL boards to 20mm wide, Wire lengths cut and whatnot. Have not completed working model yet. All hail Lady Ada!

Parts list currently:

PI 3B+
Official 7" Touchscreen
Adafruit PiGrrl Button Pad (x4)
Adafruit tactile buttons 20 pack
Adafruit 2.1w audio amplifier
Adafruit analog joysticks (PS2 type, with breadboards)
Teensy LC
DROK 3 amp 3-5.5v power supply (amazon)
Tiny voltmeter (amazon, not in v21 yet)

Have not done yet:
voltmeter placement
volume switch
power switch
any programming whatsoever

Printing all buttons at .15 and case at .2 in order to avoid friction or having to sand. I think this is my brightest idea yet!

8/25/18 UPDATE:

I am now incorporating speakers, sound holes, and a sound box in order to preserve some of the bass. The inner bracket will be incorporated into the case front in order to eliminate numbers of parts
