Small 90 degree gearbox

Building this 2 stage gearbox was surprisingly straightforward. Employing Aluminum rod for the shafts added robustness, while a couple of small ball bearings provided sufficient support. To bring it together, most parts were conveniently 3D printed. While it works decently, noise was an inevitable consequence, mainly due to the simple triangle-cut teeth design. Interestingly, this project dates back to when I first experimented with SolidWorks in its earlier days, specifically SolidWorks 98. One feature that stood out at the time was designing the top and bottom covers as a single unit. Using a knitted surface made it easy to include the desired lip. Unfortunately, I've since lost access to the detailed drawings that I had initially used for reference. To make up for this, I included a STEP file for users who work with SolidWorks import compatibility issues, enabling them to effectively use my design without running into compatibility hurdles.
