Wolverine Gauntlet: A Finger-Extension Exoskeleton

Wolverine Gauntlet: A Functional 3D-Printed Finger-Extension Exoskeleton

The Wolverine Gauntlet is a wearable finger-extension exoskeleton inspired by Wolverine-style silhouettes.

This functional orthosis is designed to assist individuals, like me, who have lost the ability to extend their fingers. While my fingers can still clench, my hands end up as tight fists. The gauntlet serves a dual purpose: it provides therapeutic benefits by stretching my fingers and acts as a prosthetic replacement for the missing extension.

Key Features

The gauntlet provides a secure and comfortable fit and a framework that

connects the wrist to the fingers.

Cantilever Springs: Utilizing 3D-printed flex material (PETG), the gauntlet

uses cantilever springs to extend the fingers.

Tool-Free Attachment: The cantilevers are hooked into anchors in the

gauntlet and then held in place using a Velcro strap, making the

attachment process convenient and easy, especially for individuals with

limited dexterity.

Adjustable Finger Rings: The gauntlet features adjustable finger rings

that can slide along the cantilever, making the gauntlet easy to adjust.

The rings are self adjust for different finger sizes, ensuring a personalized

fit.

Wrist-Friendly Fit: The gauntlet allows the wrist to flex.

Open Pull Tabs: The straps are equipped with open pull tabs, that are

easy to pass a finger through for someone with limited grip and dexterity.Printability and Build Notes (for Real-World Makers)

Printability: The gauntlet is fully 3D printable, with the exception of Velcro straps.

Support Requirements: No parts in the Wolverine Gauntlet require

supports.

Material Selection: The design incorporates TPU and PETG to achieve

the desired functions, such as flexibility, structure, spring and comfort.

How It Works

To use the Wolverine Gauntlet, simply insert your handthrough the two straps, keeping the straps

loose, and place the finger rings. Adjust the ring position and strap tension

to achieve a comfortable fit. The cantilever springs will then lift the fingers

into extension, preventing the “locked clenched” posture.
