Stack Jack : Modular GPU Support

thingiverse

Modular support for large Graphics cards. The custom thread design allows 1.5 mm adjustments every 1/8th turn. When used with the base it has a support range of 6 to 9 inches. I was growing tired of looking at my sagging video card, it was drooping almost an inch at the end. All of the available supports I looked at had a bar that went from top to bottom of the computer case. Not very attractive in my opinion so I designed my own… File Notes: SJ_SAMPLE.stl is only for visual illustration and is not a usable file. Stack_Jack_V2.dwg – a complete set of all the parts for Stack Jack, including an extension, copies of the connectors, and a copy of the original thread profile. S-J_INT_ADJ_SLV.stl - the top portion that screws into both versions of the EXT_ADJ_SLV. S-J_*_V2.stl files are not interchangeable with the other parts because the dimensions of the connectors are different. Design specifics: Stack Jack uses a custom thread design that has peaks and valleys to enable increments of 1.5 mm that will not shift due any 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 specifically designed for a small printer. Both of the adjustment parts can easily be modified for larger printers, using a section with a length that is a multiple of 12 mm.. Some of the files have a small ring that was 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 any* Notes: Parts were printed with a raft but is not required. Some parts have hollow interiors designed into them. *Clear or translucent are great as the threads show through quite well. 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 to my dismay sagged severely under it's 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 the 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 the 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.
