This is a fully parametric, highly customizable linear bushing designed to perfectly fit whatever project you are working on—from custom 3D printers and CNCs to robotics and RC gear.

Instead of hunting for the exact dimensions you need, you can generate the perfect fit right here in your browser using MakerWorld's built-in Parametric Model Maker. Just type in your dimensions, hit generate, and get printing! No CAD software required.

📏 Parameter Guide

• ShaftDia: The diameter of the smooth rod your bushing will ride on.
• BushingHeight: The overall length of the bushing.
• ToothCount / ToothHeight / ToothAngle / ToothTipWidth: These control the size, shape, and quantity of the internal bearing ridges.
• EnableCut: A binary switch! Enter 0 for a solid tube, or 1 to slice a slit down the side (makes it easy to snap over a shaft).
• TeethRemove: If EnableCut is set to 1, this controls how wide the slit is.

🧮 How to Set Your Outer Diameter (OD)

The overall thickness of the bushing is controlled by the OD_Multiplier.

If you need the bushing to fit into a specific hole (like exactly 22mm), just use this quick formula on your calculator: 

Target Outer Diameter ÷ Shaft Diameter = Your OD_Multiplier

Example: You have a 12mm shaft, but the hole it needs to fit into is exactly 22mm.

• 22 ÷ 12 = 1.833
• Just type 1.833 into the OD_Multiplier box!
