Free manufacturing file tool · STL & 3MF viewer
Inspect a 3D model in a free online STL viewer.
Open STL and 3MF models directly in your browser. Rotate, pan, zoom, confirm scale, and review dimensions, volume, triangle count, and mesh health before printing.
Parsed locally in your browser. Your file is never uploaded.
Drop one STL or 3MF model here, or
Analyzed locally; your model never leaves this browser.
How it works
Inspect a file in three steps
- 01
Choose an STL or 3MF model from your device, or open the sample cube.
- 02
The browser reads its geometry locally and reports dimensions, volume, triangles, and mesh health.
- 03
Orbit, pan, and zoom around the interactive model; confirm units when an STL has no stored scale.
From file to part
Local viewing, practical manufacturing
A browser preview helps catch scale and geometry issues before production. If you need a physical part, Kabani Tech provides 3D printing service in India for prototypes, fixtures, enclosures, and short production runs.
Opening a model never starts an order. The viewer remains a free standalone tool, and manufacturing options appear only as one quiet link after a successful preview.
Frequently asked questions
About this free viewer
Can I view an STL online for free?
Yes. Open an STL in this browser tool to rotate, pan, zoom, and inspect its dimensions and mesh without creating an account.
Does the viewer support 3MF?
Yes. The viewer supports STL and 3MF. 3MF can preserve declared model units, while STL normally requires you to confirm whether coordinates are millimetres or inches.
Is my 3D model uploaded?
No. The model is parsed and rendered locally on your device and is not sent to Kabani Tech.
Can I order a print after checking the model?
Yes. Once a valid model opens, one secondary ordering link takes you to the 3D printing workflow on Services IQ.
