CD/DVD doorstop

I decided to make a unique doorstop since I couldn't which of the other doorstops on Thingiverse I likes best.

It's customization options are as follows:

FN = 120;//$fn for cylinders (resolution)
ID = 15; //CD inner diameter - 15 recommended
OD = 120; // CD outer diameter - 120 recommended
Hmin = 5; // minimum height of doorstop
Hmax = 30; // maximum height of doorstop

The angle is selected based on the maximum and minimum heights.
