3D print model viewer
Open STL, 3MF, OBJ and PLY files in your browser to view dimensions, volume, watertightness, overhangs and build-plate fit. Files are processed locally and are not uploaded.
Drop an STL, 3MF, OBJ or PLY
The first file opens; the rest are added to the pending list
Local processing
Files are parsed in a browser worker. Parsing shows progress and can be cancelled.
Print checks
View dimensions, volume, watertightness, shells, overhangs and build-plate fit.
No uploads
No account is required. Files are not sent to a server.
How to use
Open a file
Drop a file. The view fits the model and places it on the build plate.
View the results
Check dimensions, watertightness, shells and overhangs. Use measurement or section when needed.
Adjust or capture
Change the build plate, adjust the view, or download a screenshot.
Supported formats
STL, 3MF, OBJ and PLY. Units, objects and components are read from the file where available.
Common questions
Are my files uploaded?+
No. Files are parsed and displayed in your browser and are not uploaded to a server.
Which formats are supported?+
STL (binary/ASCII), 3MF, OBJ and PLY are supported today. STEP/IGES is planned for a later release.
What if an STL has no units?+
STL does not include units. The viewer interprets it as millimetres by default and labels this. You can switch to inches; dimensions and fit checks update.
Can I use it offline?+
After the page loads, opening local files does not require a network connection.
