I liked the original design, but instead of 3D printed clips, I wanted alligator clips made of metal at the end. Therefore, I quickly started Fusion and designed a suitable adapter.
Of course, I do not want to withhold this from you.
I also modeled an alternative foot. This can be easily and quickly attached to almost any surface with blu tec.

For the rest of the parts I refer to the original designer - give him some love for this great design!
