3D Viewer & Print
Open STL and OBJ files, turn and zoom the model, measure it, change its size and estimate filament, print time and cost. Convert STL to OBJ and back. Free, private, in your browser.
How it works
- Open an STL, OBJ or GLB file, or drop it on the page.
- Turn and zoom the model, switch to wireframe or X-ray, and tap Measure to get the distance between two points.
- Check size, volume and surface area, pick a material and infill for a print estimate, then download as STL or OBJ.
Questions
Is my model uploaded?
No. The file is read and shown inside your browser and never leaves your device.
How accurate is the print estimate?
It is a rough guide from the volume, material density, infill and layer height. A real slicer will differ, mostly for time and support material.
Which files can I open?
STL (binary and text), OBJ and GLB (single-file glTF binary). Plain .gltf with separate files is not supported.
