I designed a cable tag for a USB charging cable and printed it with a 3D printer.

Recently, the number of devices that can be charged by USB is increasing. Due to USB charging, many devices do not come with a charger.
If each has its own charger as before, you may not know the purpose of the charger or you may lose it.

With USB charging, chargers are common and can be covered by a computer, so no dedicated charger is needed.

However, USB charging devices also come with a dedicated USB charging cable. This is not common.

The plug on the charger side is a USB Type-A type.

There are various devices such as USB 2.0 Micro-B, USB 2.0 Mini-B, USB 2.0 Type-C, and USB3.0 Type-C as plugs on the device side.
Not unified at this time. It will be integrated into USB 2.0 Type-C in the future.

That is, the USB charging cable cannot be used with other devices. In addition, the appearance of each charging cable is similar and difficult to identify.
In addition, my house has a lot of USB cables used for Arduino and Raspberry Pi, which is confusing.
So I signed it so that I could easily identify the USB charging cable.

The flat part of the rectangle is 30 mm wide, 8 mm high and 1.2 mm thick.
The inner diameter of the hole that fits a 3.0 mm diameter cable is designed to be 3.4 mm.
The notch was designed 90 degrees from the center of the circle. The wall thickness of the part that fits the cable is 3.4 mm.

Filament:PETG. Surface: 3 layers. Infill:20% .No brim, no raft,no support.

When I put it in the wire, it stopped and did not come off.
It's been about a week since I installed it, but it didn't loosen.

Most USB charging cables have an outer diameter of 3mm, but the electric screwdriver was 4.5mm, so I made it 4.5mm.

The character part was printed and pasted with a label printer.
