A functional 3D print!
It's a simple cupholder that can be attached to any of my sister's wheelchairs/devices so she can drink without needing supervision or someone to hold the cup for her.
Modelled in Maya (in about an hour)
Sliced in Cura
Printed in blue PLA on my Ender-3 (in about 8 hours)
Sanded and metal components added & installed - functional.
