I designed this clip so that you could thread some material/thread through the eye hole, for a means of securing the pacifier to your person. Very hand for them close by when on the move with a baby.

The clip is designed to be used with 9.5mm hole for the thread/material fixing and 23.5mm x 2mm diameter for the main body; though you can change the scale in your slicer for the 'Z' if required.
