All manufacturing and part costs were covered by Hack Club through their Outpost program (https://outpost.hackclub.com), which I am very grateful for.
Keycaps are custom from Hack Club for Outpost, product photos (top of the README) were taken in Vienna, Austria.
The JLC BOM covers the majority of expenses:
