Customizable 3D Models for Assistive Devices: Development and Future Directions of a Parametric Platform

Abstract

The authors present the development and implementation of a parametric customization service for 3D models of assistive devices on “COCRE HUB,” a web-based platform aimed at promoting independent living for persons with disabilities and the elderly. The proposed service enables users to generate personalized 3D-printable models by adjusting dimensional parameters via a browser-based interface. Developed using JavaScript Solid Modeling CAD (JSCAD), the system is intentionally designed to be accessible to non-specialists. Usability evaluations with experienced occupational therapists confirmed the system's practical effectiveness. This paper elaborates on the technical framework, development process, and user feedback, and explores its future potential and social significance.
