Do you have an old Hit Box arcade case that lacks a proper USB passthrough, has an out dated PCB, and the 4th button for Touch Pad Click? Did you know the thin metal used in the case is very easy to drill with a step bit? With this jig you can get your extra 24mm button perfectly aligned and add mounts for a Neutrik USB passthrough with a clean perfectly aligned set of holes. 

The jig is laser cut on demand from 1.5mm acrylic. It may be clear, white, black, red, or whatever acrylic I have available that is the right size.

To use:

1. Remove the bottom panel of the Hit Box controller.
2. Remove the PCB from the controller to ensure metal shavings do not cause shorts during drilling and subsequent use.
3. Remove the stock USB cable and the 3x 24 mm buttons. Cover the metal front with painters tape.
4. Place the drill guide over the three stock holes and reinstall the buttons to hold the jig in place.
5. Use a small 3mm drill bit (slightly smaller than a 1/8") to drill the 4 guide holes in the jig.
6. Remove the buttons and the jig.
7. Use a metric step bit to drill the new 24mm hole and a 19mm hole for the Neutrik pass through.
8. Remove the tape.
9. Reinstall the buttons, including your new 24mm button.
10. Install the Neutrik Passthrough (with or without a gasket/aluminum surround)
11. Connect a short internal USB cable between the passthrough and the stock pcb.
12. Connect the new 24mm button to the fighting board.
13. Replace the bottom panel.
14. You can slide the jig down to add more holes as required (L3, R3, etc.) and they will all be perfectly aligned and centered on the case.
