An addition to @LAYLITY's excellent desktop accessories. This is a smaller, tighter version of his cup holder.
The author remixed this model.
This is a version of @LAYALITY's cup holder. The diameter is smaller since I have smaller coffee cups and they would rattle around in the larger version. Also, the space for the cup's handle is smaller to hold the cup in place really firmly. This is because I'm a clutz and would spill the coffee if the cup wasn't firmly in place :-)
