SVG Key Tag Maker
Convert SVG artwork into a shallow 3D key tag. Extrude its complete outer silhouette downward for a solid backing, then raise the filled artwork or its outline above the top. Set both heights in millimetres, preview the model, and download STL or an editable 3MF.
Two heights, one printable model
The base top is Z = 0. For a 2 mm base and 1 mm text height, the backing runs from −2 to 0 mm and the raised artwork from 0 to +1 mm, making a 3 mm total thickness. The base fills the inside of the complete outer contours; holes remain visible in the raised artwork. Filled artwork is the default. Outline only creates an inward rim along the artwork’s boundaries.
For separate letters or shapes, enable Join separate base pieces to add thin connecting bridges beneath the artwork. You can adjust bridge width and add an optional base margin. Inspect the final dimensions and preview: added margins or bridges can enlarge the backing. With bridges disabled, disconnected artwork produces separate solids.
Use a circle already in your SVG
Enable Add hole to existing artwork, click the circle’s centre in the enlarged SVG preview, and set its hole diameter. The red overlay shows the proposed opening. Use the X/Y percentage fields or arrow keys for precise adjustment. The cut goes through the backing and raised artwork without adding another circle. It must leave at least 1.2 mm of backing around the opening. Its position and diameter are saved in your 3MF.
Top key-ring loop
Enable Add top key-ring loop & hole to attach a circular loop to the top of the backing. Adjust the inner hole diameter (2–10 mm) and outer circle diameter (6–20 mm). At least 1.2 mm of material is required around the hole. The opening passes through every layer. The loop is included in the final tag dimensions.
Preparing your SVG
Upload a plain SVG with solid filled vector paths, up to 4 MB. Convert live text and strokes to paths first, and unlink clones. Embedded images, external references, masks, clipping and gradients are unsupported. Simple paths, rectangles, circles, ellipses and polygons, group transforms, fill rules, inline styles and simple CSS classes are supported. White shapes cut away the raised artwork in drawing order.
Have PNG or JPG clipart? Use Image to SVG first. The tool reads SVG physical dimensions where available, trims blank margins, and lets you change the artwork width and height. SVGs without physical dimensions use 96 dpi; review the size before exporting. Artwork dimensions can be 0.5–300 mm, base height 0.4–20 mm and text/artwork height 0.2–10 mm.
3MF: save and update your design
Download 3MF for a millimetre-based model containing separate Base and Raised artwork parts. The file also contains the original SVG and the tool’s settings. Upload that original 3MF here to restore the dimensions, heights, outline mode, bridges and key-ring loop, then make changes and generate it again. Editable 3MF uploads can be up to 40 MB.
3MF geometry remains a mesh, not a parametric Fusion feature history. Reopening here regenerates the saved SVG/settings; it does not recover later mesh or slicer changes made in another app. Keep your original download, since other software may remove the embedded project. Preview colours are included as display materials, but filament assignment depends on your slicer.
Export and print
Images and geometry stay on your device. Processing runs in your browser with no conversion service or paid API. Download STL and import it into Fusion or your slicer as millimetres. STL does not contain unit or colour metadata; preview colours distinguish the two layers only. STL retains its negative base coordinates. The 3MF assembly is placed on the print bed while its base and artwork retain their shared design coordinates.
This is a layered extrusion tool for flat tags and signs. Curves are approximated with fine segments, and small details need review. The 3D preview requires WebGL 2. Test your material, small features and layer heights with a sample print.
