About

Grid frame and diffuser for two 16×16 WS2812 matrices side by side — the 115 × 115 mm panels marked 16D×16D-256LED-115×115MM on the back — as driven by the AtlasCube LED-matrix VU meter.

Diffuser for panels with a rim. I slightly filed down the tabs so they would sit closer.

3MF / STL go straight into the slicer (3MF keeps several bodies in one file). STEP opens in any CAD program, Fusion 360 files keep the full design history for changes.
