Relevant Occupations: Driving and Community Mobility

Client Factors: May be relevant when grip strength or wrist and forearm range of motion is reduced.

Performance Skills: The wide handle lets the client grip and turn the cap with the whole hand, requiring less pinch strength.

Safety Considerations: Confirm it fits the person's specific gas cap before use. The screw-on knobs and pin can loosen, so check or glue them to prevent the tool from coming apart over time.

Limitations: Gas cap shapes vary by vehicle, so it may not fit every cap. The knobs and pin can work loose. It is not a cleared medical device, so its use must be a clinical decision made by the treating occupational therapist.

Issues: None

Recommendations: Ensure that you duplicate the knob and handle before printing. Depending on the print quality, supports may hide the alignment pin hole between the handles post print.

Ease of use: Easy

Test results or review: The device works as intended.
