About this 3D model

I was looking for a clip that was simple, but looked good. There were designs on MakerWorld, but there were a few problems with them that I didn't like. Most importantly is that the clip was not very tight. So I decided to make my design that contains two magnets in the inside to help keep both joints together. In order to print this design you need to pause the print at layer 121 and place a magnet inside. The stronger the magnet the stronger the joints connect Magnet used (http://tinyurl.com/mwvt848c) - I recommend using really strong magnets Dimension: Clip: Circumference - 38mm, height - 18mm Max size magnet to put in slot: Circumference 10.5mm, thickness - 3mm Magnet used: Circumference 10mm, thickness - 3mm
