Magnetic item / necklace holder

My daughter wanted something to hang her necklaces from, and her desk has metal-backed dry erase panels on the walls of the hutch, so I designer these little magnetic push pin style necklace holders.  They have a groove to help keep a necklace on them, and can also be used as a “push pin” on a metal backed dry erase board or other metal surface, such as a refrigerator, to hold papers or pictures in place.  I used 3mm high x 6mm diameter magnets that I found on Amazon.  The magnets press fit into the hole in the bottom, but depending on how your printer is calibrated, might need some glue to keep them in place.

I printed these at 5 top layers, 4 bottom layers, 2 perimeters, 15% infill - PLA is about 11 minute print, so I usually print 6 or so at a time.
