screw to the side of a hakko fa400 solder fume extractor to mount a 1/2" flexi coolant hose to attach little grabby hands, alligator clips, pcb mounts, whatever work holding you like.

i had to insert some m4 heatset inserts into the fume extractor for mine (a knockoff from the usual suspects), and used some 5mm M4 countersunk screws (because that's what was spare in my toolbox)

prints well oriented with the screw thread pointing down, print one copy mirrored for the opposite side (3mf file included for how i oriented it, used bambu x1c with polymaker petg filament)

used these parts for the arms:
