Cup Holders

[vex]

Build a single insert/slide piece from aluminum. The housing is spring loaded with a lock lever on the left side. The insert is a sheet of aluminum with two holes cut in it for insertion of the cups. Install unit between radio and vents, or between climate control unit and vents.

Since the insert is made of a single sheet of aluminum the cups will be held by the fact that gravity will pull the tapered cup to be seated snuggly into the holder. However you'll need some cups to see what size will work the best.
