How to design a 3D-printed stamp and its handle

Stamp Maker designs a stamp and its handle that screw or twist together, ready to print. Pick a round, square or oval plate, add text in eight fonts (straight or on an arc), icons, shapes, an SVG or a picture traced into outlines, make the design raised or recessed and download 3MF or STL. It runs in your browser; designs without Pro features download free.

What can you make with Stamp Maker?

Stamps from 10–150 mm across, with up to 40 texts, icons and shapes on the face. Makers print:

  • A round shop stamp with the shop's name on an arc and its logo.
  • Journaling and scrapbook stamps with icons and short words.
  • Labels for gift wrap, coffee bags and envelopes.
  • A recessed name stamp, where the background inks and the letters stay clear.

How do you design a stamp, step by step?

Stamp Maker is a free editor: add things from the rail on the left, place them on the face, and set the plate, the handle and the download in the tabs on the right.

  1. 1. Shape the plate

    In the Face tab, pick a rectangle, a circle or an ellipse and a size (round from XS round, S round, M round, L round, XL round), or type your own. Then raised (the design inks) or recessed (the background inks), its depth, and a single or double border.

    Stamp Maker's Face tab: the plate shape and size, the relief and the border, beside the stamp's face.

  2. 2. Add text, icons and artwork

    Add text in 8 fonts, straight or on an arc, an icon, a shape, an SVG, or a PNG or JPEG traced into outlines. Drag each into place on the face, or type its position, size and turn.

  3. 3. Pick the handle

    In the Stamp & Handle tab, choose a thread (M10, M12, M16) that screws on or a bayonet (Ø 20, Ø 24, Ø 32) that twists to lock, the base's height and the colours of the base and the handle.

  4. 4. Check it and download

    The checks beside the title say whether a line is too thin to print or the mount fits the plate. Download 3MF (each colour its own body) or STL, the stamp, the handle or both; the face is mirrored, so the print reads the right way round.

    The Download tab: 3MF or STL, the stamp body, the handle and one colour.
    The download: the stamp and its handle.

Which stamps can you start from?

Each example opens in Stamp Maker as a new design, beside your own.

  • Round logo stamp

    A name on an arc round the top, with an icon and a star under it.

    • Ø 35 mm
    • Arc text
    • M12 thread
    • Free
  • Admit one

    • Recessed
    • M10 thread

    The round logo stamp inside a decorative wave ring that follows the plate.

    • Ø 40 mm
    • Decorative ring

Print the stamp body face up and the handle on its domed top, as they download; neither needs supports. The layer height is a starting point for your slicer; a thin line prints best from one and a half nozzles wide.

FilamentLayer height to startThinnest wallSupportsNotes
PLA0.2 mm0.8 mmNoneCrisp edges; sand the face lightly for an even print.
PETG0.2 mm0.8 mmNoneTougher for a stamp in daily use; clean off any strings on the face.

Tips for a stamp that prints clearly

  • Sand the face lightly on 200-grit paper: it evens the impression.
  • Keep lines at least one and a half nozzles wide, or they print thin and break.
  • A recessed stamp inks the background: keep its letters bold.
  • Ink the stamp lightly and press it straight down.
  • Before you print, check it on the view's bar: Dimensions shows its size, Measure the distance between two points, Section cuts it open and Layers steps through it as your printer will.

What if a line is too thin or the handle does not fit?

The checks say a line is too thin
Make the text or the stroke bigger, or print with a finer nozzle.
The mount does not fit the plate
Pick a smaller mount or a larger plate: a thread needs the plate 4 mm wider than it.
The back fillet is refused
Keep it under half the base's height.
Letters are missing from a text
Pick another font: the letters it lacks are left out.
The artwork is too detailed
Simplify the artwork or remove an element.
