Free 3D printing tools
Check models before you print, turn photos into lithophanes and reliefs, estimate filament and cost, convert between STL, OBJ, 3MF and GLB, inspect G-code layer by layer and calibrate your printer. Models are processed on your device, never uploaded.
Ready to use
- STL · 3MF · OBJ
STL viewer
Open STL, 3MF, OBJ, PLY and GLB models in your browser: rotate, check dimensions, volume and watertightness before printing. No upload.
- photo → STL
Lithophane maker
Make a lithophane from any photo: flat, curved or a cylinder lamp shade. Set thickness and frame, preview in 3D and download STL or 3MF. Free.
- ₾ per print
3D print price calculator
Work out what a 3D print costs and what to charge: filament, electricity, printer wear, labour and failed prints, in Georgian lari. Estimate weight from an STL.
- m ⇄ g
Filament converter
Convert 3D printer filament between metres and grams for 1.75 and 2.85 mm PLA, PETG, ABS, TPU and more, and find out how much is left on a spool.
- STL ⇄ 3MF ⇄ OBJ
3D model converter
Convert 3D models between STL, 3MF, OBJ, PLY and GLB in your browser, one file or many at once. Private and free — nothing is uploaded.
- layers · time
G-code viewer
Open G-code from Cura, PrusaSlicer, OrcaSlicer or Bambu Studio (.gcode.3mf) and preview it layer by layer in 3D, with print time, filament and weight.
- E-steps · flow
Printer calibration calculator
Calibrate your 3D printer: new E-steps (Marlin) or rotation_distance (Klipper), flow rate from wall thickness, and scale for shrinkage. Step-by-step.
- PNG → STL
Image to STL relief
Convert a logo, drawing or photo into a 3D-printable STL relief: raised logo on a plate, stamps (mirrored), signs and photo reliefs. Preview in 3D. Free.
