This is a LED Clip for the 1515 Extrusion.
Although it is designed for the WS2818 5V RGB Led Strip it should fit something 10mm wide and 2mm deep.
Credits: This is a variation on the Jon's LED Clip found in the Voron Mods Github which I found didn't hold in the extrusion and would drop out. This version is also smaller and includes an end piece.
The author remixed this model.
