I have recently obtained a friend's old Formlabs Form 2 SLA printer. I I am an absolute beginner to printing, but I am pretty excited to get into it.

However, the only place that I would realistically be able to put it is on my desk in my bedroom. From everything I've read, I need a better ventilated space with more tolerance for a mess than I could possibly provide.

I think that the right call is to just sell it and save up for some FDM printer, but at the end of the day, I have the SLA printer in hand.

I am asking whether these concerns about resin printers are really that bad and if I am actually fine to start learning printing with what I have in my bedroom.

TLDR:

If I use SSH as a Tor hidden service and do not share the public hostname of that service, do I need any more hardening?

Full Post:

I am planning to setup a clearnet service on a server where my normal "in bound" management will be over SSH tunneled through Wireguard. I also want "out of bound" management in case the incoming ports I am using get blocked and I cannot access my Wireguard tunnel. This is selfhosted on a home network.

I was thinking that I could have an SSH bastion host as a virtual machine, which will expose SSH as a a hidden service. I would SSH into this VM over Tor and then proxy SSH into the host OS from there. As I would only be using this rarely as a backup connection, I do not care about speed or convenience of connecting to it, only that it is always available and secure. Also, I would treat the public hostname like any other secret, as only I need access to it.

Other than setting up secure configs for SSH and Tor themselves, is it worth doing other hardening like running Wireguard over Tor? I know that extra layers of security can't hurt, but I want this backup connection to be as reliable as possible so I want to avoid unneeded complexity.
