The OpenBuilds Interface can be physically stacked on top of your OpenBuilds BlackBox to make an all-in-one control unit:

1. Disassemble the Interface by removing the 4x M3 x 12mm screws from the front panel
2. Lift the touch button panel off the Interface
3. Remove the back panel with the spacers still attached, from the Interface and set aside (will not be used for the Stacked assembly)
4. Remove the 4x M3 x 6mm screws that hold the BlackBox's top cover in place and set aside (will not be used for the Stacked assembly)
5. Replace these with 4x M3 Hex Standoff: 12mm Female x 6mm Male (remember to add to Cart and order ahead of time if you plan on doing this) to hold the top cover of the BlackBox in place.
6. Lower the main board/side panel assembly of the Interface onto these new spacers
7. Reposition the Interface's button panel onto the Interface
8. Re-install the M3 x 12mm screws removed in step 1
