3D STL Editor — open, edit, export
Load a real STL file, resize it to exact millimetres, rotate, mirror, arrange several models together, and download the result as a new STL — all in your browser, nothing uploaded anywhere.
Files
Tip: drag & drop .stl files straight onto the 3D view. Click a model in the view or the list to select it.
Bed
Select a model to edit it.
3D Text — emboss & engrave
TextFont
Height mm
Depth mm
Load a model first to emboss or engrave onto it — or add text on its own for plaques and keyrings.
Apply to model
Select the green text object, position it on the model (it sits slightly into the surface on purpose), then Emboss or Engrave.
Export
Exports binary STL with all edits applied. Want us to cut, carve or print it? Send it with a quote request — the enquiry form accepts file uploads.
QUICK GUIDE — Open or drop an STL → click it to select → type exact sizes in mm (proportions stay locked unless you untick) → use the arrows in the view to move it, or the rotate/mirror buttons → add a name with the 3D Text panel and emboss or engrave it → Download. Everything runs locally in your browser: your files never leave your computer until you choose to send them to us. Works with files up to ~60MB; very heavy scans may be slow on older devices.
