A versatile tool, this invention is highly valued by handy individuals. Durable and long-lasting, it can be a lifesaver for engineers or technical people. If you own a house, consider getting one as it may come in handy someday. The model showcases contour lines adjusted from various renderings, all sourced from the toon material library (except for three photo-realistic images). This is a bladder valve, an essential device that can save you money in the long run. Although difficult to find in hardware stores, it's a plumber's trade secret. The model was created and rendered by me using KeyShot 4.1's Toon material library. You can access it on GrabCAD's Workbench or view different configurations. Note: It is not a marital aid; it won't improve your relationships.
