I'm forever trying to keep these wires in the correct position to solder, so here is a jig for a 13.35x13.35mm Cree COB

The jig holds a standard 2 wire cable in place for easier soldering. I printed in PETG using a 0.4 nozzle and a 0.2 mm layer height on a MK4 with Matte Black Prusament.

I soldered SAC305 with the iron at 340 C with no problems (there is an air space under the COB for cooling).

The COB is quite a tight fit, so I used a file to remove any imperfections on the internal sides but it didn't take much.

It worked pretty well first time. I also used a pair of forceps to push down slightly on the insulation of the wire being soldered while it cooled to keep it in place.
