Disney Passholder Magnet

This is a variation of the classic Disney Passholder Car Magnet. It's a work in progress as I'd like to clean up the line work and correct my heights, but it should be adequate for now. I wanted a Magnet that wasn't completely flat. The cutout on the back is for the Magnetic material, but you can also use foam tape to adhere it to something more permanent. I have magnet sheets, so I based the thickness on those.

I know I could have thrown an SVG into Inkscape, fixed it up, then imported it into Fusion360 to extrude but this was an exercise in using the various tools available. Any recommendations for future fixes would be appreciated.
