Stack Jack : Modular GPU Support

thingiverse

Human: Supporting large Graphics cards with custom thread design. 1.5 mm adjustments every 8th turn are made possible by this unique feature. When used with the base, it provides support for graphics cards ranging from 6 to 9 inches in length. I was tired of looking at my sagging video card, which drooped about an inch at the end. All available supports I looked at had a bar that went from top to bottom of the computer case. This wasn't attractive to me, so I designed my own. File Notes: SJ_SAMPLE.stl is only for visual illustration and cannot be used as a usable file. Stack_Jack_V2.dwg - A complete set of all parts for Stack Jack, including an extension, copies of connectors, and a copy of the original thread profile. S-J_INT_ADJ_SLV.stl - The top portion that screws into both versions of EXT_ADJ_SLV. S-J_*_V2.stl files cannot be interchanged with other parts because the dimensions of the connectors are different. Design specifics: Stack Jack uses a custom thread design with peaks and valleys to enable 1.5 mm increments that won't shift due to vibration but will turn freely with little effort. A copy of the original thread profile is included with Stack_Jack_V2.dwg. The parts for Stack Jack were designed specifically for small printers. Both adjustment parts can easily be modified for larger printers using a section with a length that is a multiple of 12 mm. Some files have a small ring used to increase the area of the raft during printing and reduce the chance of failure to stay attached to the print bed. Print Settings Printer: M 200 Rafts: Yes Supports: No Resolution: User preference Infill: Solid, hollow, or light Filament: any any *Clear or translucent are great as the threads show through quite well. Notes: Parts were printed with a raft but is not required. Some parts have hollow interiors designed into them. Post-Printing Print cleanup and assembly: The base and S-J_INT_ADJ_SLV had little if any needed cleanup other than removing the raft. S-J_EXT_ADJ_SLV had stringing inside the top portion. Partially inserting the inside piece several times cleared all of the artifact remnants. How I Designed This Inspiration, aggravation, and gratification: When I put together my newest computer, I installed a large high-powered graphics card that sagged severely under its own weight. I didn't like any of the commercially available supports so I chose to design one myself. With many years of experience using AutoCAD and other design programs, it wasn't long before I produced this project. Requirements: Adjustable but resistant to vibration that may come from fans on the graphics card. Modular construction because of limited build size on my printer. I first printed the test pieces for the locking parts. After adjusting tolerances, I began printing the actual parts. Despite a few failed prints, I soon had a working prototype that is now supporting my graphics card.
