Parametric Rod & Dowel Creator

Use the Customize Button

To create your own custom rod click the "Customize" button to enter your specific dimensions and generate a custom STL in seconds.

Features

• Fully Parametric: Adjust diameter and length to fit any project—from tiny shelf pins to long structural dowels.
• Integrated Support System: The script automatically generates custom supports tailored to your chosen angle.
• Easy Removal: I've engineered a precise "air gap" between the support and the rod. It provides enough stability for a clean print but snaps off effortlessly once finished.
• Smart Safety Checks: The generator includes a built-in error notification that will alert you if your desired length and angle exceed your printer's maximum print height, ensuring you never start an impossible print.
• OpenSCAD Powered: Optimized for the MakerWorld Customizer for a seamless "No-CAD-required" experience.

Material

PLA works great for general use, though PETG is a fantastic alternative if you need increased durability

Background

This project started with a specific problem: I needed 6x356mm metal rods for a Folding Door Wine Box, but I wanted a fully 3D-printed solution instead.

Standard vertical or horizontal prints often suffer from two issues: they are either too weak (layer lines) or too long for the print bed. This Parametric Rod & Dowel Generator solves both. By printing the rod at a specific angle, we achieve two major benefits:

1. Superior Strength: Printing at an angle allows the filament layers to wrap more effectively, providing better structural integrity than a standard vertical print.
2. Maximum Length: By utilizing the diagonal space of your printer’s build volume (the "cube"), you can print rods significantly longer than your bed dimensions.

Your support helps me keep refining my OpenSCAD tools and sharing more functional designs with the community. Don't forget to upload a make. I’d love to see what you’re building!

Enjoy your custom builds!
