This is a clip to fit the M8 studding / rods of a reprap mendel machine and hold any wires / cables down to the rod.
It can be used instead of zip ties (I had to cut many zip ties again during my mendel build). The CableClippy can be re-opened with ease and helps to keep your cable chaos neatly arranged :)
Make sure your printer is able to do the fine lines. Print multiple parts in one session to get the best results (cooling...). Clip the finished CableClippy on any M8 rod and cross/hook in the two "tentacles" as soon as you have all cables caught between them.
