Cover for drinking glas (insect protection)

You are all familiar with this situation in summer: Sitting outside (terrace or balkony), want to have a drink and suddenly many wasps appear. Finally the wasps are swimming in your drink. This little thing is very helpful to avoid that situation. A simple cover for your drinking glas. It has been designed to fit on a drinking glass with a diameter of 6.5 cm. This is my very first object designed using Blender software.
