Magnetic holder for magnetic cable (heated visor)

I wanted something to hold my magnetic cable for my snowmobile helmet heated visor cable. The cable end has a 15.25 mm diameter. The holder itself have a cavity for 2 10x2 magnets stacked on top of each other. I inserted a pause before the magnet is covered. MAKE SURE YOU HAVE THE CORRECT POLARITY! I also inserted a pause close to the end if you want to insert the key ring or other attachment before it closes the ring. It's not hard to put them in after but it saves your nails! 

You'll need:

- 2 (two) magnets 10x2mm that you'll stack on top of each others

- a simple split ring (see below and without the chain)

I used a .6 nozzle without supports. You may add an exterior brim if you don't trust your build plate!  THE TOLERANCES ARE TIGHT. You may also want to increase the size %.
