I started by looking through the glove dryer designs already on printables.com.  I found some nice features that I copied, particularly the raindrop shaped openings.  But none of the designs had a rectangular base and a central funnel to channel heat up when set on something warm.  So, I designed what I wanted. 

Pictures with a smooth base are a PLA print, the radiator in my office barely gets warm.

Pictures with a crenulated base are a PETG print.  This design was to have a higher strength wall to top transition.  It also adds some slanted 5mm diameter holes to channel some air to the outside of the gloves.
