Kress quick-action lock power connector

thingiverse

After converting my Kress 1050-1 milling motor to a trim router using my trim router base, I needed an extra power cable since the original one is integrated into the gantry of my CNC table. A standard Kress power cable with a quick-action lock connector costs about 25 euros including shipping, which is quite pricey, so I decided to make the connector myself. The quick-action lock connector is used by over 35 Kress tools. To create this custom connector, you will need: This printed connector (it's a no-brainer) Two 6.3mm crimp automotive-style connectors in female (cable shoes) form Two M3 20mm screws with nuts A redundant PC power cord A soldering iron Some hot glue Here's how to do it: Cut off the unused connector from the power cord. Strip the outer casing just enough to poke the two wires through the connector. Crimp and solder the wires to the cable shoes, then push them back into the connector. Use hot glue to secure the wires, which will also keep the cable shoes in place. Twist the outer cable a few times until the casing reaches the strain relief point. Put the screw and bolt in and tighten. I made two versions: one with strain relief using an M3 bolt, and another without. The latter was my first version and relies on hot glue and common sense. I printed them upright in ABS at 0.2mm with support, which is easy to remove.
