Voron skirt holder for BTT U2C

A little holder that goes in the hex pattern of the voron skirts (modeled and tested on the TinyT version) and has two  prongs spaced for the dual USB port on the BTT U2C (USB to CAN adapter) to hold it if you do not have better hard points for it.

The design is split in two parts so that the prongs can be printed in the stronger orientation, and feature a sacrificial first layer to avoid the need for a brim.
