Galactic Unicorn Pimoroni - Diffuse Cover Grid

I've designed a diffuse grid cover - a so called soft box - to have another look of LEDs.
The "little" PCB can be bought here: https://shop.pimoroni.com/products/galactic-unicorn

Inspired by Grid Clocks like this: https://www.thingiverse.com/thing:3889589

As a possibility to attach this device I've used this other 3D part with little modifications: https://www.printables.com/model/317905-pimoroni-galactic-unicorn-skadis-mount/files
