Customizable spray stencil text box

This is a parametric spray-paint stencil generator that creates a flat stencil plate with proper stencil breaks to stop letters from falling out. The goal here was a clean military / crate-label style stencil that just works you can turn bridges off. Otherwise, the built-in stencil cuts handle it automatically. Designed specifically for Makerworld’s Parametric Model Maker using OpenSCAD. Features

- Custom text (up to 3 lines)

- internal islands supported

- Manual plate sizing for proper overspray control

- Optional autosize mode with configurable border

- Multiple bridge / stencil styles: - Off – clean cut (use with true stencil fonts)

- Stencil – classic vertical stencil cuts (recommended)

- Classic – a few horizontal support bars

- Striped – heavy repeating bars for an industrial look

- Rounded corners for comfort and durability

Supported Stencil Fonts If any of these fonts are present, you can use bridge style = Off for a true font-based stencil:

- Allerta Stencil

- Stardos Stencil:style=Bold

- Saira Stencil One

If none of these are available, the Stencil bridge style will produce the same functional result using common system fonts (Liberation / DejaVu). Recommended Print Settings

- Material: PLA or PETG

- Layer height: 0.2 mm

- Infill: 100% or 3–4 perimeters

- Supports: lol

- Orientation: Flat on the build plate

For best results, use manual plate sizing so the stencil extends beyond the text and reduces overspray. Version 5 – Major Parametric & UI Upgrade as of 2/17/2025
