These squiggly little clips print in a flash and are quite handy. I've provided 3 different sizes. To print them most efficiently, use the following Line Width settings within PrusaSlicer so that they print as all perimeters with no infill or gap fill:

• Large: 0.48mm perimeters
• Medium: 0.54mm perimeters
• Small: 0.42mm perimeters

(Note: other slicers seem to treat the line width differently. In Simplify3D, I have to use line widths of 0.45, 0.50 and 0.50, respectively for Lg, Med and Sm. You should use your slicer's preview to help pick the line width that will give you all perimeter printing.)
