Cleaning tool for (Dahua) dome cameras

(Dahua) Dome cameras need at a few times a year to be cleaned on the outside (depending on weather conditions and position of the camera).To be able to clean it, I had to take a ladder to reach all the cameras. With this cleaning tool a ladder is no longer needed. Because of the shape of the cup it is easy to keep the cleaning cloth on its place.
The measurements of the cup (R=43.4mm) are just right for my own Dahua cameras, but it might fit other models and brands as well (like Hikvision)

Assembling
Mount the individual parts as shown in the drawing. The 4 screws are self tapping pan head screws 2,9 x 10mm. The other screw set is a carriage bolt M6 x 30 with nut M6. Instead of the hex nut a wing nut is applicable.
You can use and fasten a micro fiber cloth with a diameter of 12cm. Just cut it with scissors to give it the right size. It is easy to keep it on its place by e.g. an elastic hair band.
