I needed a programming clip with slightly longer arms. I also needed to be able to fit multiple pogo pin configuration (like 2X4, 1X6, 1X8, etc), so I made multiple pin holders in order to accommodate those configurations.

Additional parts:

1x 30mm M3 screw

2x 15mm M3 screws

1x 8x20mm Spring (taken from a stock E3 V2 bed)

2x thread inserts

Feel free to make it better and share your results ! :)
