The file 'Old School Clothes Pin 3D Printer Model' is (stl) file type, size is 29.4KB.
This is my take on the one piece old school clothes pin. The center bore is 1/4" (0.25 in; 6.35 mm). This should work on the drying rails on a typical folding drying rack.
The photo of it in use pins a workout shirt (polyester) on an drying rack from IKEA (brand unknown). Be careful of slick fabrics (eg: polyester, silk, etc). They can slip off if the fabric is weighted unevenly on the drying rack rail. My tip would be to pin close to a thick part of the fabric, like the collar area.
