>>> THIS IS NOT INVENTED BY ME. THIS IS INVENTED BY MARK MANGER. I HIGHLY RECOMMEND TO VISIT GROPENER WEBSITE: "https://www.gropener.com/". THERE YOU CAN BUY THE ORIGINAL BOTTLE OPENER MADE IN ALUMINUM. <<<  >>> GrOpener is the creation of Mark Manger, an Applied Artist from Denver, Colorado. Inspired by the stick & screw openers Mark encountered in Africa in the 1990′s, the GrOpener uses the same leverage principle, but in a form that allows a bottle to be opened through the act of grabbing it.  <<<  Project video in Finnish (UPDATE: ENGLISH SUBTITLES AVAILABLE) (v.3.1): https://www.youtube.com/watch?v=gM_iu6JYxDA PRINT WITH SUPPORT MATERIAL (there is a little overhang!) My first ever 3D creation! Versio 4 (updated 23.6.14): Now there is 4 different editions: - Edition one: Basic OHBO - Edition two: OHBO with magnet. - Edition three: OHBO with a coin. - Edition four: OHBO with magnet and a coin. BTW: Other side (tail) of OHBO is meant to opening cans! (You can stick it under the clip)Magnets from dx.com (here is a link: http://www.dx.com/p/10050078w-round-ndfeb-magnets-silver-50-pcs-239991)  Coin is a basic 1cent euro coin. You will also need some super glue if printing a Edition 2,3 or 4. All editions are right scaled and tested. I recommend to print with 100% infill (layer height 0.2mm). My prints are PLA plastic but I think that ABS is even better because it is harder and stronger! I hope you to make one! I like to see how is your own bottle opener like!visit: http://www.thingiverse.com/thing:269463
