Press the Customize button to customize!

This OpenSCAD script generates a highly customizable bushing, designed primarily for automotive or mechanical applications where a "D-shaped" or cylindrical bushing is required. It features integrated grease management and easy installation options.

 

How To Use

1. Press the customize button
2. Change the parameters to your specifications
3. Download as STL
4. Download the sample print profile
5. Delete the samples off the plate
6. Import your STL to the print profile

Features

• Fully Parameterized: Adjust bar diameter, body size, and length to fit any application.
• D-Shaped or Round: Toggle between a flat-bottom "D-shape" for bracket mounting or a standard cylindrical profile.
• Integrated Grease Channels: Optional internal V-shaped grooves to retain lubricant and ensure smooth operation.
• Grease Injection Hole: Optional dedicated grease port at any angle and size for maintenance without disassembly.
• Easy Installation: Optional installation slit (with adjustable angle) and a splitting feature to print the bushing in two halves.
• Retention Flanges: Optional end flanges to prevent the bushing from sliding out of its bracket.

Customization Guide

Bushing Dimensions

• bar_diameter: The exact diameter of your sway bar.
• body_diameter: The outer diameter of the main bushing body.
• body_length: The length between the flanges.

Mounting & Base

• include_square_base: Set to true for a D-shaped bushing with a flat mounting surface.
• square_height: How far the flat base extends below the center of the bar.
• include_flanges: Adds 1 or 2 retention rings to the ends.

Grease Management

• include_grease_channels: Cuts internal rings into the bore to hold grease.
• include_grease_hole: Adds a hole through the body for a grease fitting or manual lubrication.
• grease_hole_angle: Position the hole exactly where your bracket or access point allows.

Installation

• install_slit: Adds a cut so the bushing can be "wrapped" around the bar.
• slit_angle: Align the slit away from the primary load direction.
• split_bushing: Cuts the entire model in half (useful for printing in two rigid pieces).

Printing Recommendations

• Material: TPU (85A-95A) is highly recommended for its durability and flexibility.
• Wall Loops: 100 loops for 100% fill and the most structural integrity.
• Infill: Shouldn't matter with the wall setting but set it to 50% gyroid.
• Orientation: Print vertically (standing up) for the best surface finish on the bore and flanges. Use supports when you have a flange in the air
