Lian Li A3-mATX — PSU Cable Cover (parametric, OpenSCAD)

A clean, parametric cable cover designed for the Lian Li x DAN A3-mATX case. It hides the PSU cable bundle visible through the tempered glass side panel, matching the white aesthetic of builds like the DeepCool PN850M.

This cover is designed for builds where the PSU is mounted in the top position of the case, as supported by the A3-mATX layout. It fits a standard ATX PSU (e.g. DeepCool PN850M or similar 150×86 mm form factor).

## Features

- Optional front / side mesh with circular hex pattern (visible through glass). pattern of the mesh matches the mesh of the case

- PSU collar: wraps around 3 sides of the PSU shroud (left, front, right)

- Cable cutout on the rear shoulder for routing

- Magnetic mount: recessed pockets for 6.2×2.2 mm neodymium magnets

- No supports required — add a brim if you have adhesion problems

- Fully parametric OpenSCAD source included
