The maker WhoIsLudwig recently published instructions for a self-printable ITX PC case called “Kubic”. The design is characterised by its compatibility with smaller 3D printers and a mix of retro aesthetics and modern functionality.
The Kubic case is specially designed for ITX motherboards and can be produced on 3D printers with a print area of just 180x180mm. The largest individual parts only require a print area of 170x170mm, which also enables production on compact models such as the Prusa Mini or Bambu A1 Mini.
In terms of design, Kubic is modelled on classic computers such as the NeXT workstations and the Apple Power Mac G4 Cube. A striking feature is the integrated carrying handle, which is reminiscent of the Nintendo GameCube, but does not affect the upper heat dissipation.
Despite its compact dimensions, the housing offers space for high-performance components. It supports graphics cards with two slots and a length of up to 220mm, an SFX power supply unit and a 140mm case fan. Ludwig emphasises the good cooling performance of the design: In games, the CPU and GPU reach temperatures of around 75°C, which is acceptable for a compact case.
According to him, it should take around an hour to assemble the case. Around 1.5 kg of filament is required for printing, whereby the developer has had good experiences with PLA. He reports trouble-free operation for two months, even under full load and with the housing closed. He recommends PETG as an alternative.
For tech-savvy hobbyists, the Kubic project is an interesting opportunity to create a customised PC housing. The detailed building instructions and 3D print files are available on WohisLudwig’s Instructables page, and additional information on the printing process can be found on Printables.
