I've been soldering those darn DSUB connectors for nearly 40 years and finally made a mount to hold them for soldering. Uses 10mmX2mm neo magnets. These magnets hold connectors in place even when wires are connected. Mounts for
DB9 M/F
DB15 M/F
DB25 M/F
PLA 15% infill, no supports. Magnets press-fit, super glue if loose. Markings are separated in STEP file for multi-color. Printed on X1C.
Happy soldering!
Included the Fusion design file.
