The arcade cabinet design is based off this project by TobiasPi https://instructables.com/Mini-Pi-Powered-Arcade-Machine/

I will be releasing the full design plans for both styles of cabinet under the same terms as the original project (CC BY-SA 3.0 license).

If you have access to a laser cutter and some 3mm birch plywood then you will be good to go.
