Thingiverse
It's a Z-Axis chain connector for the two holes, that are on the Z-Axis.You'll need some super-glue to get the two parts together and two M4/M5 screws with wide enough heads and nuts. They can't be too long, or they will block the Z-Axis movement.You can use washers too.With this design, the E-stepper motor can cool down and you don't need long M3-screws.The parts have a vertical hole for a M3 screw and nut. It can help to align the two parts together when gluing and is useful for mounting various of things.The hole behind the chain-connector can be used to zip-tie the cables.Because there's a slight left-shift, you'll need the new included frame connector too.
