How It Works

1

Try It Free

Download the standard size of any model. No account.

2

Build Your Exact Size

Create a free account and get 10 Custom Builds. Spend them on any models to build the exact sizes you need.

3

Scale Up When You Are Ready

Unlock every size of a model you use often, or go Pro for unlimited sizes on every model plus a commercial license.

Designed for the printer

Every model engineered for real-world print results.

Flat bases. Overhangs kept within forty-five degrees. Tolerances tuned for common nozzle sizes. Designed to load, slice, and print without the guesswork.

No Supports

Every model designed to print support-free.

Metric + Imperial

Pick the exact dimensions you need in the system you think in.

Full BOM

Every part lists the hardware it needs, with buy-links.

Print-Ready STL

Load it and slice it. Pro unlocks every size, on every model.

One Model. Any Size You Need.

Every size is regenerated from the parametric CAD model, never scaled from one file. Set the dimensions and download that exact size. The ranges below are what each model publishes today, chosen by the designer rather than by any limit of the engine.

50 - 200 mm

Circular Tray

Height

20 - 100 mm

Sections

Designed for 3D printing.

Every model is designed for strength, clean aesthetics, and hassle-free printing.

No Supports Required

Overhangs stay within forty-five degrees and bases sit flat, so nothing needs support material. Leave supports switched off in your slicer, and there is nothing to break off or sand back afterwards.

Engineered for Strength

Each model is oriented so load runs across the print layers rather than along the bond between them, which is where FDM parts split first. The orientation is chosen for the stress the part will actually see.

No Toys. Real Parts.

If you're here to hoard ten thousand STLs you'll never print, this isn't your catalog. If you run a printer because something in the real world has to fit and work, you're in the right place.

StreamSolid is built for engineers, print farms, and serious hobbyists who care more about exact fit than about free.

Questions

What file formats do I get?

Print-ready STL files on every model, with the standard size free. Pro adds Custom Size on every part, built to the dimensions you need.

Can I use these for commercial products?

Personal use is the default on free downloads and one-time unlocks. Selling what you print, including bulk and wholesale, needs the commercial license that comes with Pro.

How does pricing work?

Standard sizes are a free STL download with no account. Make an account and 10 Custom Builds are included. Make any one model in any size with a one-time unlock, or go Pro for the whole catalog and a commercial license.

What if I need a size that is not listed?

Eligible models have a Custom Size panel: set the dimensions you need and we re-run the parametric CAD model in the cloud to generate that exact size. It takes about 30 seconds, because the geometry is genuinely rebuilt rather than a stored file being stretched. Once a size exists, it downloads instantly for anyone who asks for it again. A free account comes with 10 Custom Builds to spend on any models, and it is unlimited on any model you have unlocked and on every eligible model with Pro. If the part you need does not exist at all, you can suggest it on the roadmap.
