Dimensionally precise USB-C plug & receptor

These are three models of the USB-C standard, dimensionally accurate as per the USB Mechanical Group compliance [reference document](https://www.usb.org/sites/default/files/USB%20Type-C_Compliance%20Document_rev_2_0_April_29_2020.pdf) (from 2020), one for the plug, one for the receptor inside devices, and one for the plug with an opening for the contact plate (tongue) inside USB-C receptacles.

The dimensions are as follows:

Plug:
Width: 8.25mm
Height: 2.40mm
Depth: 6.65mm

Receptor:
Width: 8.34mm
Height: 2.56mm
Depth: 6.69mm

Tongue cutout (in plug with opening):
Width: 6.83mm
Height: 1.30mm
Depth: 4.65mm

IMPORTANT:
Remember that USB-C slots have a plate inside them. Because of this, the simple model for the plug won't fit into a USB-C slot. If your use case includes plugging into a USB-C slot, use the model with the opening for the tongue.

While these models are dimensionally precise, the USB standard has a tolerance of up to 0.06mm to these dimensions, and especially the depth m
