Magnet-Tag Generator

A customizable OpenSCAD generator for magnetic nametags.
Text, font, size, margins, rounded corners, magnet placement, and text style are fully parametric.

Features

• Configurable tag size derived automatically from text and margins
• Bold toggle for the text
• Text can be extruded outward or inverted (cut into the tag) with adjustable depth
• Smooth rounded corners with a single radius parameter
• Automatic magnet hole placement with configurable max spacing — adapts to tag width
• Adjustable magnet tolerance for dialing in the perfect fit on your printer
• Visual indicators for the thin floor under magnets in preview mode
• Uses Liberation Mono for consistent cross-platform rendering

Usage

Online

1. Click on "Customize"

Local

1. Download and open the .scad file in OpenSCAD.
2. Tweak the parameters in the Tag and Advanced sections at the top.
3. Press F5 to preview, then F6 to render.
4. Export to STL for printing.

Print Tip

Add a pause to your print at the layer just above the magnet cavity (magnet_under + magnet_height + magnet_tolerance). This lets you drop the magnets into the holes before the printer seals them in. In most slicers you can add a pause via a height-based color change or custom G-code (M0 or M601). With the default settings this is at 2.6 mm (0.4 mm floor + 2 mm magnet + 0.2 mm tolerance).

Parameters

Tag

Name	Type	Default	What it does
input	string	"Custom Text"	The main text displayed on the tag.
bold	bool	true	Toggle bold text.
text_size	mm	10	Height of the text.
text_invert	bool	false	Cut text into the tag instead of extruding outward.
text_depth	mm	0.4	Depth of the text extrusion or cut.
margin	mm	3	Margin around the text on all sides.
tag_radius	mm	3	Radius for all four rounded corners.
magnet_diameter	mm	6	Diameter of the magnet holes.
magnet_height	mm	2	Height of the magnet holes.
magnet_tolerance	mm	0.2	Extra clearance added to the magnet cavity diameter. Increase if magnets don't fit, decrease for a tighter hold.

Advanced

Name	Type	Default	What it does
magnet_under	mm	0.4	Thickness of the floor under the magnets.
magnet_above	mm	0.6	Thickness of the ceiling above the magnets.
font_factor	float	0.8	Width factor for text width calculation. Calibrate to your font.
magnet_max_spacing	mm	30	Maximum distance between magnet holes before an additional hole is added.
name_line_spacing	float	1.5	Line spacing multiplier for multi-line names.
tag_color	color	"white"	Color of the tag body.
text_color	color	"black"	Color of the text.
