This is remixed from https://www.thingiverse.com/thing:2652714. I wanted something slightly smaller but with the same size based (I use 3M VHB tape to stick it to things). This has a diameter of 6mm vs the original having a 12mm diameter.
Print with the loop flat on the bed and no support materials are needed. This orientation will also make the loop stronger.
