Recently I purchased some bumper stickers from Sticker Mule to use and give away at a couple upcoming Maker Faires. Though I’m extremely happy with how they turned out and how fast they got here, I decided later that I wanted these in magnet form. Though normal refrigerator magnets are OK, they really don’t stick as well as perhaps they should, and I decided to make my own with my CNC router and Neodymium magnets that I had left over from another project. The results can be seen below:
As mentioned early in the video, I meant to have the magnets stick out of the back of the assembly, but ended up covering them up with a sticker instead. This left some indentions in the sticker, but it still sticks to a surface quite well. I shouldn’t have made that mistake, but when designing in 2D, a part has to by absolutely symmetrical about one axis if you’re going to flip it and expect it to work.
Obviously this is quite a simple build, and one that could be done manually if needed. I tried to highlight the CNC process with some interesting views in the video, stationing a GoPro camera inside the machine itself. Hopefully you enjoy!
World Maker Faire
If you’d like to see this device in person, I’ll be at the Wold Maker Faire in New York this weekend, and plan to have at least one of these attached to my backpack. If you see it, please say “hello” – I’d love to meet you!
On another note, I purchased the bumper stickers used here from “Sticker Mule.” I was extremely pleased with the quality of the stickers, and how fast they shipped them to me. If you’re interested in getting your own custom stickers, use this link to get a $10 credit for both you and me!
