Customisable Ring Box

Created this because I was procrastinating work.

It's customizable, just load it into your favourite 3D modelling software and change the diameters of the circles.

The holes on the sides are for 6mm magnets. You need 8 of them. Or, alternatively, you can extrude one side of the holes up past the surface by 3mm to make it like a peg fitting thingy. Just makes sure its not too tight or you might not see your ring again.
