If you don’t care for the looks, just put it down where needed, and fix it to whatever is around with cable ties.
I did the same in my daughters shared accommodation. Officially they had wifi in all the student rooms, but my daughters room basically had no reception, so I ran a cable from the other end of the flat where the router was down the staircase into her room for a local AP. When she moved out, it was a quick job with a pair of pliers to get it out again.
Got a bunch of RPIs, some of them retired.
One of the active ones runs a MediaWiki engine (if it detects my home wifi on startup, it acts as a mirror slave to the master installation on the server, if not, it opens a wifi with my home wifi’s credentials and offers the wiki as read-only).
Another one runs a DB that controls a number of ESP8266 clients controlling lights, motors, and sensors.
I use “radicale” as calendar server for the family. Thunderbird can talk to it directly, on Androidd, I use DAVX5 to sync them.
I run several instances of mediawiki. Sometimes I curse the programmers for being jockeys (next to no usable documentation, every update breaks something), but at the end of the day it’s easy and works.
Maybe the reason is that you behave like a first-class asshole idiot? You wanted help, but evaded the reasonable question for your instance name. Several times. While making unreasonable demands. I’ve seen a lot of idiots in thirty years of being on the internet, and seriously, you are one of the bigger ones.
A good search engine would be quite important. One thing that annoyed me back on the site that should not be named was that their search engine was completely useless - It was not even capable to find posts where I entered verbatim text of.
Having a good search engine that can actually find a post I was looking for would be a major plus for the fediverse.
