Assembly Process: Feed a zip tie through the two rectangular holes on the printed part. Secure and tighten the zip tie through the zipper on the clothing. Cut the excess zip tie flush to avoid any sharp edges.

Functional Use: This device is a small printed pull that attaches to a zipper slider with a zip tie, giving a larger surface to hold so a person can work the zipper without pinching the small tab. It prints in five sizes.

Relevant Occupations: Dressing

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

Performance Skills: The larger pull and loop let the client grip and move the zipper rather than pinching the small tab.

Safety Considerations: Cut the zip-tie end flush after fitting so there is no sharp edge against skin or clothing. Confirm the tie is secure through the slider.

Limitations: Some zippers are too large for the design. Fit is set by the printed size and the zip tie. It is not a cleared medical device, so its use must be a clinical decision made by the treating occupational therapist.

Issues: Some zippers may be too large for the design.

Recommendations: Print all five zipper designs to use as references when choosing the correct size for the user.

Ease of use: Easy

Test results or review: The part works as intended and may be scaled to fit certain zippers when necessary.
