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

cults3d

This bottle opener should fit on every plastic bottle with a cap diameter of <30mm like water bottles, Coca Cola bottles, etc. Originally I created this for my grandma who has trouble opening water bottles by hand and struggles with regular openers. But with this make, she can open such bottles much easier now. I hope that especially people who have the same struggle, can make their life at least a little bit easier with this opener! Share a Make and let me know how it works :) What you additionally need: Steel File 2x 20mm M3 Screws 2x M3 Nuts An M3 x 16mm screw for fastening the attachment would be fine too. You need to shorten it anyway for the ideal fit, so it doesn't matter. 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. 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. I would appreciate it when you donate what this design is worth in your opinion!
