Header Pin Soldering Jig

thingiverse

Makes soldering PCBs easier by holding header pins perfectly perpendicular. Sometimes, a bit of light sanding with a fine file is necessary to remove small rounded corners made during printing. The jig's depth might also need adjustment to fit the headers properly, making them sit flush with the surface. The pin type or brand isn't certain, but they were included with a UNO prototyping shield and are roughly 2.5mm thick and 10mm tall.
