Show HN: Control multiple 3D printers from a single Raspberry Pi

I built a web service to help manage large printer farms after creating a solution for my brother's online shop with 40 printers.

The system uses NATS for comms between Raspberry Pis and the backend, with each cluster isolated via separate NATS accounts.

Users can download a custom Pi image with pre-configured node credentials.

Based on testing, each Pi can reliably handle 10-20 active printers. Scaling is straightforward - add more Pis to manage more printers.
