Tees to convert hanging lights that just have two wires coming out of the top into a Tee style hanger that can be clipped on to a supporting wire. I'm specifically using these for Govee Outdoor String Lights H7021
The AutoDesk Fusion file is parameterized so it should work to adjust the wire diameter and case dimensions to adjust the print for different sizes of wire.
I use zip ties or twist ties to keep the clips firmly closed. Printed with Prusament Black PETG on a MK3s. Hanging the clips looks great with these ⅔" black binder rings: https://www.amazon.com/gp/product/B0B6W3SGH6
