About this 3D model
This is a cable holder that mounts to one slot of an aluminum extrusion. This will allow you to route cables around extrusions and keep your printer or other project that uses the extrusions tidy. I use these to hold the USB cable coming from my printer off to the side, and they work beautifully. I provided the .step file if you would like to modify the design, as this model is designed for a 3.5mm diameter cable to fit very snugly.
