The provided video tutorial can be found in the 'Files' section. I created a parametric model due to lack of reusable models at my workplace for a specific project. The model allows users to alter the mounting hole parameter and regenerate the design as per their needs. At that time, I had no idea about its dimensions or specifications, but I needed various lengths which weren't available in any existing models. Some designers even mirrored models and trimmed them to desired lengths. Interestingly, a few designers had years of experience, yet they couldn't provide a parametric model. Creating such a model should be straightforward, but my experiences have been different.
