Outer Cap Generator

Introduction

Do the legs of your furniture, the ends of wooden frames, or exposed pipe edges scratch your floor, rattle, or make unwanted noise?
This outer cover generator lets you easily design custom-fit protective caps that slip over the outside of objects—tailored exactly to your measurements.

Based on the entered dimensions and corner radius, it automatically switches between circular, rounded, or square shapes, while allowing precise control over wall thickness, bottom thickness, and total height.
It's ideal for furniture legs, wooden posts, pipes, enclosures, and more—designed for real-world use and easy to print.

Recommended Material: TPU or TPE
For best flexibility, fit, noise reduction, and durability, we strongly recommend printing with flexible filament.
PLA or PETG can work for rigid needs, but soft materials bring out the full benefits of this cover.
