Mug and glasses holder-FreeCAD

I needed to replace the old glasses case I was using to hold my computer glasses when I was not at the computer and to hold the old coffee mug (that has a history) I used as a pencil holder.  I wanted to hold the mug so the two would stay together.  I was tempted to just add a built-in pencil holder to the glasses holder to replace the mug, but since I have not drunk coffee in decades and have since used the mug as a pencil holder, I decided on the design here.  To make the model more universally usable, I might add a design like that if it might be useful to someone.  Since it is parametric, I have included the FreeCAD file so it can be modified to fit your needs. 

I included a picture of what it replaced, it installed in place, and one with the glasses cleaning cloth I keep under the glasses (I tend to get lots of fingerprints on my glasses).  Enjoy…
