Improved parametric cupholder mount for phone or tablet

Parametric phone mount that allows customization to fit many cars and many phones. Measure your phone (in its case if that applies) and your cupholder, set the measurements and print. Tapered base for a snug fit, and options to deal with a variety of phone and tablet designs, USB cables, and aesthetic choices.

It's somewhere between remix of and inspired by this design:

A more or less standard angled cellphone holder that fits in a cupholder, but it:

• Has a tapered outer sleeve that fits snugly into a tapered cupholder without rattling around.
• Has an outer sleeve and separate cylinder base for snug fit and easy rotation of the phone holder.
• Allows for a angled cut that follows the phone holder smoothly down the cylinder base to keep a longer USB connector from binding.
• Adds optional side wings in addition to the side walls. You can either use them to save printing by having sides at the top and bottom, or if you have a flared cellphone protective case, you can position the wings closer together than the lower side walls.
• Allows for different lengths for the left and right sides of the USB cutout for side mounted USB connectors.
• Allows for rounding of the USB cutout channel.
