Device Details
Overview
The Bottle Opener is a simple, low-cost, 3D-printable handheld tool to help those with arthritis, limited finger dexterity or other related disabilities open or close plastic screw-on caps on various beverage bottles, cleaning products, condiments. The bottle opener allows users to remove or replace the lids of these jugs with a small squeeze on a large, rounded gripping surface. The Bottle Opener has several modified versions to open different sizes of containers. The different sizes are named by the approximate diameter of the caps they can open in millimeters.
Usage
Slide the toothed gripping surface on top of the lid of the container, then while squeezing the handle to grip the lid, twist either the container or the device to remove or screw on the lid.
Cost
The cost of this device includes only the filament used to 3D print the device/devices. Each device requires slightly over $1 CAD worth of PLA filament.
