🧤 Sleeve

📌 What

A general-purpose 3-sided U-shaped sleeve that slides onto a HomeRacker support. Lock pin holes on both sides secure it in place.

🤔 Why

A reusable attachment primitive for anything that needs to sit on a HomeRacker support — connecting rack columns (Racklink), labeling rack sections, or mounting custom accessories.

🔧 How

Open parts/sleeve.scad in OpenSCAD and use the Customizer panel.

Parameter	Default	Range	Description
`length`	3	1–20	Sleeve height in HomeRacker units
`debug_colors`	false	bool	Color-code geometry for debugging
`disable_chamfer`	false	bool	Remove chamfers (useful for debugging fit)

Library usage — include in your own model:

include <../sleeve/lib/sleeve.scad>

sleeve(length=3);

Implemented as a BOSL2 attachable. An optional color parameter overrides the default yellow.
