The Kraken PCB holder and soldering station

After trying to print my own arms using PETG and PLA+ I decided to order two sets of these arms (not an affiliate link) for $13 and am super happy with the results.

I am using this switch and these clips (also, not affiliate links).

Pretty much any 3mm bolts will do as long as they're not too long. The switches I chose have holes that are the perfect size for threading 3m bolts from the top. The kit I have is this one, but you can find them anywhere.

The base of this is meant to fit this popular PCB vise which is why it is such a strange shape. Your vise should snap into place, but may require a little sanding to fit.
