Rectangular 3D Models: Cases, Boxes and Lids

This collection gathers rectangular cases and boxes for 3D printing, from simple storage containers with lids to customizable enclosures and phone or PC cases. You can also find gear-driven case models that show internal mechanisms. Use the filters to narrow by size, lid type, or mechanism. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Rectangular 3D Models: Cases, Boxes and Lids»

Rectangular cases range from plain lidded containers to parametric boxes where you set the dimensions. Some models focus on a closing method, such as magnets, a spring lock, or a sliding lid. Others are device-specific, like phone cases or PC enclosures, and a few are working gear or transmission case models.

On the author's model page, check the outer dimensions and wall thickness, the number of separate parts, and whether the lid needs magnets, screws, or a printed hinge. Look at the material and settings the author lists, and review photos of real prints to judge how the lid fits. For boxes with moving gears or locks, confirm the clearances and assembly order before printing.

If you need a different shape or function, try search terms like enclosure, container, housing, or tray alongside rectangular. Related topics include parametric boxes, stackable storage, magnetic lids, and modular cases. Adding a device name or a mechanism type, such as gear or lock, can narrow the results further.

FAQ

Frequently asked questions

What does 'parametric' mean for a rectangular case?
A parametric model lets you change dimensions or features in the source file before exporting an STL. The author usually explains which parameters are editable.
How do I choose between a magnetic lid and a snap-fit lid?
Magnetic lids need magnets of a stated size and give easy opening; snap-fit or sliding lids rely on printed geometry. Check the model page for the required hardware and clearance.
Can I scale a rectangular case to fit my item?
Scaling changes wall thickness and the fit of lids or moving parts. It is better to use a parametric model or adjust dimensions in the source file.
What should I check for a case with a working mechanism?
Look at the assembly instructions, the number of parts, and the clearances the author lists. Photos of real prints can show how the mechanism moves.
