Tiny cable clip for 20x20 extrusion

This is a simple, teeny little clip to hold wires inside the slot of a standard 20x20 (or 20x40, etc.) aluminum extrusion. I found that gently squeezing the prongs with a pair of pliers made them much easier to install. They can be removed by inserting the short end of an allen key through the channel between the prongs and then using it as a lever against the extrusion to pull the clip out.

I'm using these to tidy up the extruder cable on my Anycubic Kossel printer.
