I would recommend prowlarr instead of jackett for indexer management, and pihole as at least an additional blocking service but in reality it’s really all you need for use at home. I’d also strongly encourage use of a VPN on your *arr download services. I use a separate box to run Plex and then have my *arrs all running on their own VM inside if it to provide separation and allow be to more easily segregate the network traffic (as someone that doesn’t really know docker that well it “just works” for me. Also probably worth looking at how to store your media on an external target, it’s easy to quickly accumulate 10s of TBs of media and trying to store that all on the server locally is asking for trouble. Better to set everything up on a NAS to start.
Please keep in mind that you need to seal that print before you use it with food. Because of the layers, there’s are a ton of places for dirt and bacteria to hide that are impossible to clean. Additionally, depending on what kind of nozzle you used, heavy metals can end up in your print which you don’t want to then leech into your coffee. General advice is to just not use 3d prints first good, but if you really want to you should coat them in a food safe epoxy before using.
