A logo I made some time ago but couldn't upload it. Hopefully, this is my last try.
It is made in the almighty Inkscape, which is in my opinion the OpenSource app with the highest number of features. Also, it uses my most favourite font, that is called Ubuntu and is used as the default font in a linux distribution of the same name. [link]
The logo represents precision and is designed in a way that it is really nice even when it is printed on the ten years old metal plate located in the middle of the building area
