P.B.C.O. - Plastic Bottle Cap Opener

prusaprinters

<p>This bottle opener should fit on every plastic bottle with a cap diameter of &lt; 30mm like water bottles, Coca Cola bottles, etc.</p> <p>Originally I created this for my grandma, who has trouble opening water bottles by hand and struggles with regular openers. I tried various versions until I eventually came up with this design. Now she is finally able to open bottles by herself again.</p> <p>What you additionally need:</p> <p>Steel File<br/> 2x 20mm M3 Screws<br/> 2x M3 Nuts</p> <p>An M3 x 16mm screw for fastening the attachment would be fine too but you need to shorten it anyway for the ideal fit, so it doesn't matter.</p> <p>Make sure that you sharpen the other screw, with a file like it is shown in the pictures. It acts as a tooth for the bottle cap and it may not work properly otherwise.<br/> A too-long screw also harms the functionality, so if it doesn't work well for you, try to shorten the screw a little bit more.</p> <p>Happy printing! :)</p> <h3>Print instructions</h3><p>For the handle is no additional support needed!<br/> You can remove my custom support with a screwdriver or knife afterward.</p>
