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

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. I tried various versions until I eventually came up with this design. Now she is finally able to open bottles by herself again.

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 but 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.

Happy printing! :)

For the handle is no additional support needed!
You can remove my custom support with a screwdriver or knife afterward.
