extrude-js

Framework-agnostic parametric T-slot extrusion profile generator using JSCAD.

Generates accurate 3D geometry for custom T-slot extrusion profiles with correct slot, trapezoid channel, center hole, and rounded corner geometry.

Install

npm install extrude-js @jscad/modeling

Usage

import { createExtrusion } from "extrude-js";

const geometry = createExtrusion({
  size: 20,
  length: 100,
  centerHoleDiameter: 4.19,
  slotWidth: 5.26,
  slotDepth: 1.5,
  innerWidth: 11.99,
  trapezoidBaseFromCenter: 6.34,
  cornerRadius: 1.0,
});

Export to STL (Node.js)

import { createExtrusion } from "extrude-js";
import stlSerializer from "@jscad/stl-serializer";
import { writeFileSync } from "fs";

const geometry = createExtrusion({
  size: 20,
  length: 100,
  centerHoleDiameter: 4.19,
  slotWidth: 5.26,
  slotDepth: 1.5,
  innerWidth: 11.99,
  trapezoidBaseFromCenter: 6.34,
  cornerRadius: 1.0,
});

const stlData = stlSerializer.serialize({ binary: false }, geometry);
writeFileSync("extrusion.stl", stlData.join(""));
