3D Models for 120 mm Fan Cases and Enclosures

This collection gathers STL files for compact cases, fan housings, and modular cooling parts. You will find designs for single-board computers, small devices, and mechanical boxes. It helps when you need a printable enclosure and want to compare mounting options.

«3D Models for 120 mm Fan Cases and Enclosures»

The models range from simple fan grills and spacers to full enclosures for boards and drives. Some are single-part covers, while others use multiple pieces, screws, or snap fits. Fan-oriented designs often focus on airflow openings and mounting hole spacing, whereas device cases add walls, ports, and lids.

When choosing a model, check the listed outer dimensions, wall thickness, and the number of parts. Look at whether the author shows supports, infill, layer height, and material recommendations. Photos of real prints can reveal gaps, warping, or tight clearances that a render may hide.

To narrow the search, try related terms such as fan housing, enclosure, spacer, bracket, and electronics box. You can also search by device type, for example single-board computer, drive caddy, or gear case. Combining a size with a function often returns more relevant results than a single broad word.

FAQ

Preguntas frecuentes

What should I measure before printing a case?
Measure the board or fan footprint, mounting hole spacing, and the height of any connectors. Compare these values with the dimensions listed on the model page.
Do these models need supports?
It depends on the design. Check the author's notes and photos; some parts print without supports, while overhangs or bridges may need them.
Can I resize a case for a different fan or board?
Scaling changes wall thickness and hole sizes, so the original hardware may no longer align. Look for a model drawn for your dimensions or adjust the source file.
How can I find a matching lid or base?
Search for modular, stackable, or snap-on parts and check the mounting pattern. Many designs share common fan or board layouts, but you should verify the dimensions on each model page.
