This design aims to replace conventional sheet metal cases with a robust case manufactured through injection molds or investment casting. The case is designed to be stiff, featuring plastic extruded tubes that protect against damage in the event of a fall. It boasts easy assembly and compact packaging, utilizing tubes on the exterior and extruded angle irons inside for reinforcement. The strength of this design lies in its joints, which are held together along both the interior and exterior edges, reducing the number of required parts by integrating hex screws into the panels. The current weight estimate for an aluminum model is 16 lbs. It is designed to accommodate Mean Well LRS-350 350W AC/DC Power Supply and M4-ATX, 250w Automotive DC-DC Car PC Power Supply, allowing for operation with both 120V AC and 12V DC. A custom power supply designed to bolt onto the interior bottom panel is proposed as it would utilize the aluminum construction for efficient heat dissipation. The CAD file is fully parametric, enabling dimension adjustments to meet specific size requirements. Three provisional patents have been filed to protect this innovative design. A YouTube video showcases an updated model, and renderings and videos can be found at droppable.org. Note that the Yang Ji Rampage V Extreme motherboard and Titan video card used for rendering are not included in the files.
