You should now have a finished macro-pad. You can change the key configurations to make it easier to use your favorite CAD software, or add some hotkeys for gaming and productivity. If you want to make your macro-pad even cooler, check out the appendix for some ideas on using different materials and manufacturing processes for the case and other parts. If you have feedback about the project, or want to add your completed macro-pad to the Garage Makes display, send us an email. Thanks for completing this project!

Project Modification Ideas
Some of the parts of the macro-pad can be constructed in different ways than the ones described in these instructions:
Case:
- CNC Machine machine it, either from wood using the CNC router, or from metal/plastic using the CNC mills.
- Use the resin (SLA) printers to print a translucent case with a very smooth finish.
...
- Cut it out of a thin sheet of wood veneer using the CO2 laser cutters.
- Make it out of metal sheet with the fiber laser.
- Make a plastic of or carbon fiber plate using the water-jet cutter.
Key caps Caps & key switchesKey Switches
- Use the vinyl cutter to make labels for the key caps.
- Print your own key caps using the resin (SLA) printers.
...
- Use the PCB mill to make your own PCB - This will be a particularity particularly challenging modification!
