Magnetic headphone holder

This is a remix of the headphone holder posted by Boogie. I didn't want to screw holes into my desk, so I redesigned the holder to receive magnets so that I could attach the holder (and my headphones) to the side of my computer. I've printed one already, but had to make some adjustments, so I'll attach pictures of the finished product once I print it. **Adjustments made today (1/4/2020), I've uploaded the new gcode that I used. I got rid of some imperfections and switched to PETG instead of PLA. No real reason for the filament change except that it was the only orange filament I had. Looks and functions great.
