About this 3D model

This bottle opener should fit on every plastic bottle with a cap diameter of < 30mm likewater bottles, Coca Cola bottles, etc. Originally I created this for the elderly who have trouble opening water bottles by hand and struggles with regular openers. With this opener, they should be able to open bottles by themself again. What you additionally need: Steel File2x 20mm M3 Screws2x 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. Share your make and let me know how it works for you! :) Happy printing!
