The flat space over the heater control is handy, but there is nothing to keep things placed there from vibrating off.  I designed a fence to be attached containing the area.  The part has a inside flange with screw holes, but double sided tape should be just fine.  If there is sufficient interest I will print and offer them to the group.  These are printed in carbon fiber reinforced polycarbonate.  A premium material that is very tough.   
Let me know what you think.
Before; Note the little USB charger port by the vent.

After;

I thought about putting a bottom liner of the the same material as used in toolboxes.
