This is a simple holder for supporting an H-bridge (for controlling motors) and Arduino Nano v3. It consists of two parts which, after making mechanical connections, must be connected, e.g. by gluing or welding. The Arduino Nano located at the top (photo) was finally attached by inserting the filament into its mounting holes using a 3D pen.

What you see in the photo was printed on an Easythreed X1 printer. I used these elements to build a car wiper motor servo, which can be controlled via USB via the Discord instant messenger.
