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

Stamp Maker guide · NabiMakes Tools · Updated 3 November 2026 · https://nabimakes.com/tools/stamp-maker/guide/

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. 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.

### 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. 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. 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.

## Which stamps can you start from?

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

## Which print settings work best for a stamp?

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.

| Filament | Layer height to start | Thinnest wall | Supports | Notes |
| --- | --- | --- | --- | --- |
| PLA | 0.2 mm | 0.8 mm | None | Crisp edges; sand the face lightly for an even print. |
| PETG | 0.2 mm | 0.8 mm | None | Tougher 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.
