Mini ITX Computer Case - Modular / Stackable

thingiverse

This is a project I have been working on for some time. It is the original purpose for which I bought a 3D printer and is finally coming to fruition. This design will require onboard power or pico-PSU style power supplies, for now. Project Goals: Modularity - Inspired by Legos Stackable - Each self-contained module can be stacked in a tower Minimalistic - Small footprint, as little wasted inner space as possible Print-ability - No supports, little waste, low warp risk Marketability - Anyone interested? There are two version to choose from: The slim version is for Slim-ITX boards and does not allow space for hard drives. The standard version should fit any ITX board and has space for two hard drives with the included bracket. Future Plans: I'd like to add modules to hold various PSU and VGA cards. This will enable this case to be used for a gaming or desktop style system. If anyone would like customization, please message me. Additions: 3.5 inch Hard Drive Module (currently untested, 1/27/17) Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: No Supports: No Resolution: 0.2 Infill: 10% Notes: I have designed this project around a 0.4mm nozzle and 0.2mm layer height. For best results, print at or below that resolution. I used an average infill of 10%, more can be used if you choose. Some light cleanup should be all you need post-print. Parts Breakdown ITX Stacker - Top or Bottom: This part caps off the top or bottom of the case. It will require excellent bed adhesion and a brim is recommended. Estimated weight: 47g ITX Stacker - MB Tab Lock: These tabs are screwed down to lock the motherboard in place with normal case screws. No brim needed. Estimated weight: 0.15g ITX Stacker - Flange: The flange is designed to be an optional spacer between systems when stacking. It will require excellent bed adhesion and a brim is recommended. Estimated weight: 20g ITX Stacker Slim - Back Blank Panel: This panel can be used as is or for making custom I/O ports. Print face down; bed surface will determine a matte or shinny finish. ITX Stacker Slim - Back Panel with Wifi: This version includes a mount hole for a wifi antenna. Print face down; bed surface will determine a matte or shinny finish. ITX Stacker Slim - Back Plate Corner: This corner differs from the universal corner in that it has space cut out to allow for the I/O panel to fit into the back panel. I recommend this be printed with three universal corners. Face their inner areas towards each other and set layer start to nearest. This will keep the visible surface clean and pit free. Estimated weight: 2g ITX Stacker Slim - Front Blank Panel: This panel can be used as is or for making custom I/O ports. Print face down; bed surface will determine a matte or shinny finish. Estimated weight: 15g ITX Stacker Slim - Front Panel with Power and LED: This panel I have customized for a small power button and LED. The area over the LED is only 0.2mm thick to allow for the light to bleed through, yet invisible when off. Print face down; bed surface will determine a matte or shinny finish. Estimated weight: 15g ITX Stacker Slim - Single Fan Panel: This panel includes a mount point for a single 40mm fan. Print face down; bed surface will determine a matte or shinny finish. Estimated weight: 14g ITX Stacker Slim - Universal Corner: This corner is to be used on any of the corners except the one the back plate I/O panel cuts into. I recommend this be printed as a set of four with a back plate corner. Face their inner areas towards each other and set layer start to nearest. This will keep the visible surface clean and pit free. Estimated weight: 2.5g ITX Stacker Slim - Vent Panel: This panel has vents for airflow into or out of the stack. Print face down; bed surface will determine a matte or shinny finish. Estimated weight: 13g ITX Stacker Standard - Back Blank Panel: This panel can be used as is or for making custom I/O ports. Print face down; bed surface will determine a matte or shinny finish. ITX Stacker Standard - Back Panel with Wifi: This version includes a mount hole for a wifi antenna. Print face down; bed surface will determine a matte or shinny finish. ITX Stacker Standard - Back Plate Corner: This corner differs from the universal corner in that it has space cut out to allow for the I/O panel to fit into the back panel. I recommend this be printed with three universal corners. Face their inner areas towards each other and set layer start to nearest. This will keep the visible surface clean and pit free. ITX Stacker Standard - Dual Fan Panel: This panel includes a mount point for two 40mm fans. Print face down; bed surface will determine a matte or shinny finish. ITX Stacker Standard - Front Blank Panel: This panel can be used as is or for making custom I/O ports. Print face down; bed surface will determine a matte or shinny finish. ITX Stacker Standard - Front Panel with Power: This panel I have customized for a 16mm anti-vandal power switch. Print face down; bed surface will determine a matte or shinny finish. ITX Stacker Standard - Hard Drive Bracket: This bracket is mounted to the bottom of the motherboard and has space for two 2.5 inch hard drives (currently untested). ITX Stacker Standard - Universal Corner: This corner is to be used on any of the corners except the one the back plate I/O panel cuts into. I recommend this be printed as a set of four with a back plate corner. Face their inner areas towards each other and set layer start to nearest. This will keep the visible surface clean and pit free. ITX Stacker Standard - Vent Panel: This panel has vents for airflow into or out of the stack. Print face down; bed surface will determine a matte or shinny finish. Assembly To create one "module" you will need three universal corners, one back plate corner, and a combination of the four side panels. The fan panel and vent panels can be swapped and doubled up, should you choose a passively cooled or intake/outtake fan setup. Multiple modules can be stacked up to accommodate the number of systems you have. The flange can be used optionally to visually separate the modules. The top or bottom part only needs to be printed twice, as any expansion will only increase the height of the stack. All modules in the stack are bound together with #10-32 threaded rods. These are cut to length with a cap nut on each side. The rods will only need to be recut if more modules are added to the stack. Glue may also be used between the corner and side panel joints for extra rigidity, but not necessary.
