Wheelchair cup holder

thingiverse

Cup holder that attaches to the metal tubes on a wheelchair viat tie-wraps. it apparently fits the nexus walker as well (23mm tube diameter). i printed mine pretty roughly, 0.8mm nozzle @ 0.3mm layer height. 0.8mm wall thickness (1.6mm walls in the design makes them solid),1.6mm top and bottom. works like a charm. it swivels, and will slide down to the next supporting ridge on the tube - some rubber or anti slip coating would stop that though.
