Functional Use: This device is an opener with a large loop to hold and a jaw that grips a plastic bottle cap. The person fits the jaw around the cap, holds the loop, and turns, so the teeth catch the cap and twist it off. It prints in five sizes for different cap diameters, and the narrow end can also help lift a can pull tab.

Relevant Occupations: Feeding and Eating

Client Factors: May be relevant when grip strength, pinch strength, or fine motor control is reduced.

Performance Skills: The client holds the bottle with one hand and turns the opener with the other. The loop gives a wider surface to hold and the teeth grip the cap, so removing it does not come down to pinching the small cap.

Safety Considerations: The jaw grips best when it matches the cap size, so one that is too big or too small can slip while turning. Confirm the cap size before use.

Limitations: Each printed size fits a limited range of cap diameters, so a person with different bottle sizes may need more than one. The person still supplies the turning motion. It is not a cleared medical device, so its use must be a clinical decision made by the treating occupational therapist.

Issues: None

Recommendations: Confirm the size of the user’s bottles before choosing which opener to print.

Ease of use: Easy

Test results or review: The part worked as intended.
