Spray paint stencil maker

Stop struggling with paper stencils that tear or bleed under the spray can. This parametric stencil generator creates sturdy, reusable painting templates with perfectly calculated bridges so your letters never fall out. Whether you need a military-style crate label or a clean custom sign for the garage, this tool generates a flat, reusable plate that works instantly.

🧠 Behind the Design (For Makers & Moderators)

This is not a basic 2D text extrusion. This is a fully parametric OpenSCAD algorithm that dynamically calculates and generates structural bridges for floating typography (preventing inner-letter dropouts like the center of an 'O' or 'A'). It also computes adjustable solid boundaries for overspray protection, making it a functional, structurally complete stencil tool rather than a simple text-to-STL conversion.

âš™ï Customizer features:

Text input: Add up to 3 lines of custom text.
Overspray control: Adjust the border size manually to protect your surroundings from stray paint.
Bridge styles: Choose between Classic, Striped, or the standard Stencil cuts. You can even turn bridges “Off†if you select a true stencil font.

ðŸ–ï Print settings:

Material: PLA, ABS/ASA or PETG. It doesn't really matter even TPU will work fine.
Layer height: 0.20mm gives a solid, flexible plate.
Supports: None. Print it completely flat on the build plate.
