The author remixed this model.
This mod replaces the center rear skirt on a VORON 2.4r2 (for 300mm and 350mm sizes only) with one that has two of the hexagons opened to accept an insert that will clamp a Parametric Umbilical Gland (PUG) adapter. This can be used to pass through CAN bus, Beacon or other cables through to my other mod that provides dual PUG adapters on the upper rear panel inlet.
There are also options to print the VORON logo in another color using a multicolor system such as BoxTurtle.
Print with standard VORON part settings, and secure PUG insert from the rear of the skirt piece with M3x6 screws (BHCS or SHCS).
