32 Key Macropad
assembled into a 4x8 macropad.
This is running the same

A single board 16 key version is
Gateron clear PCB mount switches. Grab bag SA profile keycaps
Arduino Micro clone attached to the bottom of the PCB.
M2 spacers and screws hold the PCBs to the aluminum plate.
Sanded down the aluminum plate with 220 grit sandpaper to smooth the sharp edges and the burs on the drilled holes.
