Ashtray-Replacement Cup Holder

Two-piece cup holder replacing the original dashboard ashtray, explicitly designed for 903-series vans. The creator states that a spring must be added for the mechanism; source imagery shows the installed holder, loose physical parts, mechanism and CAD views. Use cabin-heat-resistant material and a securely retained spring, preserve controls and selector clearance and test only with closed cold containers until retention under braking is confirmed.
