Sharing this reddit thread because I was looking to solve this problem myself and thought that the needle-probe approach linked was terrific!

Interesting, I liked the flexibility of his idea to use coolant hoses, or 3d printed parts to make coolant hoses. But It may be that I just want to toss something together real quick instead of asking for a second set of hands or eyes. I wonder why he updated his design to the newer one you posted?

Came to upvote this. The station works unreasonably well. The needles are pointy enough that they deform solder/copper a little bit and stay put once placed (you can flex the arm to preload the needle). You can buy it on the maker's website in the second link, with all the bits for ~50eur. Naturally this is no good for high frequency, but it has saved me countless hours of soldering and removing fine wire in the lab.
