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.
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.
Practical Parts, Sized to Fit
Find useful parts for your workshop, home, and projects, then choose dimensions that fit. 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 unlimited Custom Builds on eligible parts, 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. StreamSolid Pro is coming soon with unlimited sizes 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. Existing sizes download instantly after you unlock them. Each new size you unlock uses one Custom Build, and repeat downloads use none. A free account comes with 10 Custom Builds to spend on eligible 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.
