Grommet /Bezel / Cable entry that holds a USB plug or socket (moulded cable type) into a panel.
USB plug/socket on a cable is pressed into the rectangular hole in the grommet, and retained by friction and by a clamp screw.
A ring on the inside retains it.
A screw holds the ring to the flange, and bites into the USB.
Grooves allow for burrs around hole in the panel.
A Key is provided for anti-rotation, and to locate the ring to flange for easy assembly.
The small flat ended plastic screws commonly used to screw onto plastic pillars are ideal for the locking screw.
Customised the USB x,y dimensions for a tight fit on your plug, and the panel thockness and hole size.
You might find that parts of the flange on the short side of the usb plug are too thin to print or break off - don't worry about it.
Most of the USB dimmensions have no effect - they just change the rendering of the usb plug.
Printed at 0.35mm on my UP Mini.
