Printing Tips
Material
PLA works for most cases. Use PETG or ASA if the part sits near a heat source like an ASIC exhaust.
Layer Height
0.2 mm gives a good balance of speed and quality. Use 0.12 mm for visible display pieces.
Infill
15-20% infill is sufficient for cases and stands. Increase to 40%+ for structural mounts that bear weight.
Supports
Most models are designed to print without supports. Check the model notes if supports are needed for specific orientations.

What file format are the models in?
All models are provided as STL files, the universal standard for 3D printing. STL files are compatible with every major slicer software including Cura, PrusaSlicer, Bambu Studio, and OrcaSlicer.
What 3D printer do I need?
Any FDM printer with a build volume of at least 200x200x200 mm will work for most models. Popular options include the Bambu Lab P1S, Prusa MK4, and Creality Ender 3 V3. The Space Heater XL may require a larger build volume.
What material should I use?
PLA is fine for most cases and stands since they are not near direct heat. For parts exposed to ASIC exhaust (like heater enclosures), use PETG or ASA for better heat resistance. Avoid standard PLA for anything near sustained temperatures above 50°C.
Can I sell prints made from these files?
Yes. The CC BY-SA 4.0 license allows commercial use. You must credit D-Central Technologies as the original designer and share any modifications under the same license.
I don't have a 3D printer. Can I order a printed version?
Absolutely. Each model has an "Order Printed" button that links to the professionally printed version in our shop. We print in-house with quality PLA/PETG and ship directly.
Will you add more models?
Yes. We are in the process of open-sourcing our full library of 50+ designs including cases, stands, mounts, duct adapters, and accessories for Bitaxe, NerdAxe, Antminer, and more. Check back regularly or follow us on social media for updates.
Can I submit my own design?
We welcome community contributions. Send your STL files and a description to our contact page. If we feature your design, you will be credited as the original creator.
