Individuals with limited dexterity due either to problems with muscle control or to joint pain can have difficulty opening pop-top cans and opening small bottles. This assistive device makes it easier to accomplish both tasks.
The device is comprised of two parts:
- The pop-top can opener has a wedge at one end, a recessed slot to grasp the pop-top, and a rounded bottom to provide leverage to tear off the can top. It should be printed in a hard plastic like PLA, ABS, or PETG.
- The bottle opener is mounted inside the larger opening of the pop-top can opener. It is designed to grip the sides of a bottle top and should be printed out of a flexible plastic like TPU (e.g., Ninjaflex, Polyflex). If you are unable or reluctant to print with flexible filaments, you can use the pop-top opener without inserting this part.
The following video demonstrates how to assemble and use the Pop-top Can and Bottle Opener:

Before you begin, you’ll need to go to the Thingiverse page for the can and bottle opener. Select the “Files” tab and download the two STL files – one for the rigid, outer pop-top can opener and another for the flexible, inner bottle opener .
