6// todo:
7// - hinge
8// - screw holes + captive nut to mount
9// - internal mount for mcu and battery
10// - hole for usb panel mount
11// - bevel lid
12
13// maybe/wishlist:
14// - wire routing clips on panel?
15// - buttons on side for pinball?
16// - vent under mcu/battery?
17// - slant panel toward player?
18
19// bugs:
20// - hinge is not aligned -- either male arm length or connector placement is wrong
