Magnetic coat hanger for metal filing cabinets, wardrobes, or really anything metal you need to hang a coat/jacket from.  I recently started a new job and didn't have a place to hang my suit/sports jackets while at my desk.  I don't like hanging them from the back of my chair, as they can get wrinkled. I have 2 large filing cabinets by my desk and made this hanger to go on those to hang my jackets.   Prints in 2 pieces so no supports needed, use super glue or epoxy to join the two pieces and put the 3 magnets in.  I can say for sure they will hold a 3xl wool winter jacket. 

Magnets I used are magnets 32x3mm
