I altered the files to work with my 3/4″ mdf I already had, and to fit the old gateway monitor I had which fits in the the arcade ike it was designed for it, I only had to slightly increase the cutout for the screen. I bought a 1 player light up button kit from amazon, $42 well worth it, but the buttons didnt fit the holes in the original files and the joystick didnt need through hole attachment. I also wanted to add a volume knob and a usb port to the control panel. So, in the end I changed it quite a bit.
not 100% done yet. still need screen plexi, paint, and decal work but almost all the way there. I used the fake coin door found here: http://www.thingiverse.com/thing:426031
and I used Recalbox for the emulation stuff. It, for our uses, has significant advantages to retropie. – mcmasterp

I used a 1/4″ straight bit to cut everything except the screw holes.
The mortises are pocket cut .25″ deep. Screw holes are drilled with 1/8″ bit.
The screw holes are so the machine can be assembled and disassembled easily. You could easily glue permanently but I figured I would have to take it apart a few times to get the controls working properly.
The button holes are for standard 1 1/8″ buttons. The opening for the monitor might need adjust depending on what monitor you use.
