I agree but having a more reliable printer you don’t have to fix is even better. It allowed me to start teaching myself CAD and now I spend time designing stuff around the house rather than fixing or upgrading the printer. I use Alibre Design, allows you to buy outright and no subscription if you don’t mind being on an older version.

Sounds intriguing, might be able to use this with Tailscale on a home box to access it on the go.

If you didn’t need 2.5 Gbps on the network, ace magician has a ryzen 5 mini that has a 2.5 Gbps and a 1 Gbps NIC for around 300 USD. Otherwise I guess you are looking for a new pc to put in fast cards.

If you had a pc already with two NICs, you could do sophos xg home on it or a pfsense/opnsense. I’m planning on virtualizing a VM on a cheap mini ryzen box that meets that (ace magician makes one for $300).
