PC Case - CoreBOX M256

CoreBOX M256 was created from the same energy that drives every good DIY project — the need to create something of your own, functional, and simply cool. This is a case that doesn't pretend to be a factory-made product. It encourages you to touch it, modify it, paint it, redesign it, and customize it to suit your needs. It's a design for people who like to do things their own way.

With its modular frame, interchangeable panels, and full compatibility with mini-ITX and compact microATX (244x178 mm), the CoreBOX M256 is like building blocks for adults. The set includes five decorative panels, but that's just the beginning — you can personalize the front panel with your own SVG design, engraving, perforation, or anything else you can think of. There are no limits here, only creativity.

Each element is printed separately, so you can play with colors like a paint palette — subdued elegance, neon chaos, or a mix of everything at once. Best of all, most parts can be printed without supports, as long as you position them correctly. No filament waste, no stress.

And if you like the design and decide to buy it, know that you are supporting a creator who has really put a lot of work into it. I'm not aiming for Tesla, don't worry. But maybe someday I'll be able to add to some iconic 3D printer, the kind that makers talk about with a twinkle in their eyes and a slight drool. For now, a “bowl of rice” is enough for me to have the strength to keep tinkering — but every bit of support is a real boost of energy and motivation for future projects.

CoreBOX M256 is not just a case.
It's a project that gives you the tools, and the rest is up to you.
It's a space for experimentation, creation, and fun — just the way makers like it.

FAQ — Will my printer print this?
What is the minimum build volume required to print the CoreBOX M256?
Although the largest part of the enclosure is approximately 265 mm, in practice you will need an FDM printer with a minimum build volume of 300 × 300 × 300 mm.

What about Prusa?
* Prusa CoreOne L – YES
* Prusa XL – YES
Josef Prusa would probably say, “If you're going to do it, do it right” — and indeed,
only his larger machines have enough space for the CoreBOX M256 to spread out comfortably, as if on a deck chair.

What about Elegoo, Creality, and the rest of the world?
Any printer with a minimum build volume of 300 × 300 × 300 mm should be able to handle it without any problems.
* Any other “big block” that has a real 300 mm or more
If your printer has a table larger than an average pancake pan, you're in the game.

What will you need for assembly?
I wanted to keep it minimalistic, so all you need to put it together is:
4x M3 screws (Allen)
25x M2 screws (Allen)
16x 10 x 2 mm neodymium magnets (these are what make it so convenient to use!)
Glue: I recommend cyanoacrylate with an activator – it bonds the magnets to the print perfectly and instantly.

💡 Pro Tip: When assembling 29 screws, I strongly recommend using a power screwdriver – you'll save time and have a lot of fun putting it together!

Am I supporting the creator by purchasing the design?
Yes. You won't buy me a Tesla, but maybe someday you'll contribute to some iconic 3D printer.
For now, a “bowl of rice” is enough to keep me going.

Take a look at the last photo in the gallery. It shows a vision of what your final setup could look like. The case standing next to a modern printer creates a harmonious whole.

This photo is my goal and inspiration. Selling this model brings me closer to realizing this dream—purchasing a new machine that will allow me to design even better accessories for you. By purchasing this design, you not only gain a brilliant case, but you also become part of this journey!

PS. And between us, the entire CoreBOX M256 was printed on Bambu Lab printers, which worked on this project like a team of labor leaders from a 1970s poster. No complaints, no cigarette breaks, just steady, repetitive work from morning to night. Every panel, every prototype, every test — the printer did its job like a well-oiled machine with the slogan “Plan completed 200%.”
