Remix of the legendary one handed bottle opener to use these magnets http://smile.amazon.com/gp/product/B00CEB14TE?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s00. I made it few mm wider to accept the magnet and make it sturdier. I also rounded the sharp tip designed to lift up can tabs.I printed mine in .3 with a 50% hex infill, 4 perimeters, and 6 solid top and bottom layers. I used Glow In The Dark PLA and I think the stiffness of PLA lends itself to a bottle opener better than ABS. The magnets should tap right in with a hammer if you can get the same ones I did. If you copy mt settings the sucker uses about 50 grams of plastic, but it's sturdy as hell.
