Little mini embroidery hoop pendant. Printed on a Flashforge finder, no special settings. Inner hoop just pops out. Use as you would a normal embroidery hoop. Adding a little bit of your favourite fabric gives the hoops tension and holds it together...you just need to find a neat way of finishing the back (I stitched mine).
This is a work in progress as the hanging loop is a bit skinny and I had trouble threading my chain...still working on that part...
