Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V.

This may be our first sand matrix printer, but it’s not our first sand 3D printer. Fail of the Week is a Hackaday column which celebrates failure as a learning tool.
