PCB Assembly Jig

This Thing helps construct PCBs, keeping burns off the fingertips. Soldering requires heat that travels through components into fingertips holding them in place. The Thing eliminates these minor burns. Instructions You need a few non-printable parts: 1 Pair of M6 threaded rods - mine are 200mm long 8 M6 nuts and washers A lightweight compression spring, 7mm diameter around 20mm long 1 30mm M3 bolt 2 20mm M3 bolts 1 25mm M3 bolt 2 10mm M3 bolts 6 M3 Nuts Print 1 of everything except: Jaws.stl - Print 2 Long arm.stl and short arm.stl - Print 2 each Watch the exploded diagram video: https://www.youtube.com/watch?v=PE292aysC_A Attach both threaded rods through holes on frames' bottoms. Each side's rotating mechanism differs. On the locking side: Place the spring over the long pin and pass it through a frame hole. Compress slightly until the end of the pin is flush with the outside of the frame. Lock by tightening the screw. Glue an M3 nut into one jaw's back face. Thread a 25mm bolt through the locking crank and then through the long pin, and screw it into the nut. Loosen the locking screw. The spring should push the jaws toward the jig's center, pulling the crank flush against the frame. The other end is more or less the same without the spring. The board clip clips onto the PCB edge, depending on its size, make a compound arm from the short and long arms. Place components with tops up, hold parts in place with arms. Flip the board over and solder parts in place. That's it!
