Talon Flextensor 1.0

thingiverse

As requested, the Flextensor 1.0 has been launched! This innovative assistive device is specifically designed for individuals who have suffered a congenital amputation known as Amniotic Banding Syndrome (ABS), resulting in the absence of digits on their wrist and palm. The Flextensor effectively serves as a replacement fingers system, uniquely omitting the elastic mechanisms common to this type of assistive technology. There are two main advantages associated with mechanical extension systems: With elastic-based devices, users typically face significant resistance. Moreover, when attempting to grasp smaller objects, the tension from the elastics is exponentially greater. In contrast, the Flextensor empowers users with unmatched strength and control, particularly when manipulating tiny objects that demand exceptional dexterity. By employing a robust mechanical design, the user's ability to execute precise movements and tasks becomes significantly enhanced. A major concern related to elastic systems lies in their tendency to exclusively engage the flexor muscles of the wrist. This imbalanced physiology can give rise to anatomical distortions and chronic strain. The Flextensor intelligently engages both the extensor and flexor muscles, effectively fostering a more harmonious relationship between these critical components. From a therapeutic perspective, this balanced design offers preferable advantages. To fully appreciate the intricacies of the Flextensor and learn how to properly assemble it, viewers can access an enlightening video showcasing its intricate mechanisms: https://www.youtube.com/watch?v=v1Urkqoo09c&feature=youtu.be The only printed components requiring support are the rod portions. The separate file 'TFRod' requires separate printing with structural reinforcement. Printers operating on spacious bed dimensions can effectively print just TalonFlexLeft, or alternatively opt to create smaller scale devices consisting of a combination of parts such as: Alternatively for those utilizing relatively modest-sized printing beds, a few modifications need to be made in order to avoid issues related to scale. To this end, the recommended assembly configurations would entail: For users looking for a more personalized fit with smaller dimensions: As you consider the design specifications I carefully set forth during the model development stage, I want you to be aware that it was envisioned around adult users (20+). Consequently, these print parts may display considerable resistance on joint action. The size adjustment is 160%. Tolerances may indeed prove restrictive at smaller scale dimensions. Please ensure the adequate sander removal after each assembly part assembly. Alternatively for small scale, the thinner pp-sn snap-assembly with 'stl' model files are suitable solution.
