Compute the X/Y/Z bounding box of any STL, OBJ, or GLB mesh. Get exact print dimensions in mm — useful for fitting models to your printer bed.
Upload an STL, OBJ, or GLB file
We scan every vertex and compute min/max along X, Y, Z
Get the bounding box as JSON — copy or download

Whatever units the source file uses. STL is unitless — most printers assume mm. Use the 3D Unit Converter if your file is in inches.
Yes — the size dimensions match what slicers report. If the size is larger than your printer bed, scale the model with the Model Scaler tool.
We compute the axis-aligned bounding box (AABB) at the model's current orientation. Rotate the model first if you need a specific layout footprint.
Compute the exact volume of any STL/OBJ/GLB mesh in cm³ and estimate weight for PLA, ABS, PETG, resin, and 8 metals. Browser-based.
Open toolAuto-scale STL/OBJ/GLB models to fit any printer bed (X/Y/Z mm). Maintains proportions. Browser-based, no upload.
