I have not but if there was enough interest I could make a rough go at it. It's not a very complicated setup.

It's basically Alpine Linux with some custom sysctl and interface settings, sch_cake with custom settings, cdg, netfilter, Unbound DNS with some local zones for limited spam filtering and a cron based refresh of common domain names, blackhole routes for known clowns and DoH/DoT IP addresses, chronyd for NTP, dnsmasq for static and dynamic DHCP, gratuitous arp cron job to lower latency and steal back my IP if someone tries to take it and restore quickly from ISP router failover all running on a Protectli VPN class small business firewall with cron snapshots/backups from another node.

My first pass would probably just be a static page with linked text files of the configurations and a brief synopsis of what each file or in some cases individual settings are performing.
