This is a small combination of designs to make a fridge magnet that might hold keys or other such things. Designed it to use a .709" x .197" disc magnet, but have also included the sketch up file so you can make it mount however you please. Waiting on my printer, figured I would at least make some initial designs and get them into the wild. Please post your photos of results. Thanks.
Made it in Google Sketchup in inches. The Sketchup files for both the magnet version and the flat back version are available for you to modify for your mounting application. And advice/comments are always appreciated
