Wheelchair Frame-Mounted Cup Holder (45° / 90°)

This bar-mounted cup holder is designed to attach to wheelchair frame tubing using zip ties. It provides a stable, accessible location for holding a beverage without requiring permanent modification to the chair. Design Notes Secures to wheelchair frame tubing using zip ties Angled geometry positions the cup holder for accessibility while minimizing interference with wheels and controls Designed to tolerate vibration, impacts, and incidental contact during everyday use Configuration Options 90-degree version: Intended for wheelchairs with more upright frame geometry 45-degree version: Intended for wheelchairs with sloped or angled frame members Fitment & Compatibility Intended for manual wheelchairs with tubular frame members Zip-tie mounting allows compatibility across a range of frame diameters Material & Manufacturing This part is 3D-printed from 95A thermoplastic polyurethane (TPU), selected to provide controlled flexibility. The material allows the cup holder to absorb impacts and flex under load without cracking or permanently deforming, which is a common failure mode of rigid plastics in this application.
