PCB Header soldering jig

thingiverse

This enables you to use a piece of stripboard as a holder for PCB headers while soldering them on. Place the headers on the stripboard then whatever you want to solder on top of that. These are for a stripboard with a thickness of 1.2mm. Simply print and push on to the corners. I added blu-tack on each one so it wouldn't slide around while soldering. Print with the slot vertically. No supports required. I printed mine in PLA.
