Test - 3 Working as intended for all three tested devices. This third make confirms that the bracket concept works as intended across all three tested pneumatic devices. The design printed successfully, the mounting geometry worked properly, and each tested unit sat in the holder the way it was meant to. That was the main goal of this project: to create a simple but reliable pneumatic mounting bracket that can be adapted for different filters, water separators, lubricators, and similar compressed-air components. The overall print result came out clean and functional. The bracket feels solid, the wall-mount layout works well, and the support structure provides good stability without making the design unnecessarily complicated. Even though the tested devices differ in size and shape, the holder concept still performed well, which shows that the design is practical as a reusable base model. One of the biggest advantages of this project is that the SCAD file can be adjusted for different diameters, heights, and mounting-hole positions. After testing it on three different devices, it is clear that this is not just a one-off print, but a flexible bracket system that can be customized for many workshop air-line components. Overall, this make turned out exactly as planned. The print quality is good, the parts fit correctly, and the bracket works as intended for all three tested devices.
