I designed this cup holder mount for my Chevy Bolt so I can listen to my Uniden BCD436HP scanner while driving. It cants the radio at an angle and the plug is a nice snug fit in the cup holder. The Bolt's cup holder is 81mm (3 3/16") diameter at the top.
Prints without supports. I printed mine with Prusament Anthracite PETG with a 0.4mm nozzle, 0.20mm layer height, 10% infill.
Happy making!
