Case for a WS2812 LED matrix (LM-3216) — sound-reactive build

The enclosure for my light-show build: an LM-3216 WS2812 matrix driven from R1BBIT and reacting to music. The file matrix_assembled.obj is the whole assembly as it goes together — frames, back shells, the stand, the matrix board with its LEDs and the diffusing film.

Printed in eight parts. The frame and the back are split into left and right halves so each one fits a 220 mm bed, and a clip joins them at the top.

Parts

• frame_L / frame_R — 168.6 x 182.2 x 35.6 mm, front frame halves
• back_L / back_R — 168.6 x 180.8 x 34 mm, rear shells
• top_clip — 40 x 12.5 x 29.3 mm, joins the halves at the top
• diffuser — 326.4 x 165.9 x 16.5 mm, flat sheet over the LEDs
• stand — 220 x 26 x 79.9 mm, with stand_lid to close it

STEP sources exist for every part, so the mounts can be reshaped for another matrix — ask and I will post them.
