As the first results of the project, a pneumatic cylinder was modeled in SolidWorks.
The resulting model data can be downloaded here:

Subsequently, an Android app was developed that can be played on AR glasses or a tablet and displays the assembly of the cylinder step by step, thus supporting the assembler in his work. The finished app can be downloaded here:

As soon as the app is played on a terminal device, the following QR code must be scanned to start the assembly of the pneumatic cylinder:
