Issues are cooler when rack-mounted, and [KellerLab] goals to make that every one much more accessible with the HomeRacker, a modular and 3D-printable rack constructing system designed to allow you to rack-mount to your coronary heart’s content material. Whereas it will probably deal with large issues, it appears particularly relevant to duties like mounting one’s residence community tools and Raspberry Pi machines.
The fundamental system (or core) consists of three totally different components: helps, connectors, and lock pins. The helps are the primary structural bars, the connectors principally go on the corners, and the lock pins guarantee the whole lot stays put. The nominal sizing is a 15 mm x 15 mm profile for the helps, with lengths being a a number of of 15 mm.
All is designed with 3D printing in thoughts, and requires no instruments to assemble or disassemble. There are design parts we actually recognize, like how components are printed at an angle, which improves energy whereas eliminating the necessity for helps. The lock pins (and the slots into which they go) are designed in order that they’re efficient and can neither rattle nor fall out.
However the core system is simply the inspiration. There’s loads of modularity and expansions to deal with no matter one might have, from Gridfinity cabinets and drawers to numerous faceplates and different modules. There are some instance functions obtainable from [KellerLab]’s HomeRacker fashions web page, like CD shelf, under-desk drawer, or filament rack.
[KellerLab] welcomes any collaboration, so take a look at the GitHub repository for CAD references and design information.
One final level to make concerning the worth of printing objects like this at an angle: not can the ensuing layer strains present higher energy and scale back or remove the necessity for helps, however printing at an angle will help cover layer strains.
