This jig helps me to solder wires accurately to COB.

The previous design worked well for quite a long time but the wire insulation is prone to melt causing sticking to the jig.

While soldering the wires to the pads, I use metal tweezers to hold the wire in place as it cools (and to also cool down the wire a bit to prevent insulation melting).

Printed in PETG. The 3MF for the MK4S  version contains negative space for magnets 8mm x 3mm.
