Made this Stranger Things LED Lightbox.

Size is approximately 21 cm x 8,5 cm x 3,5 cm, but you can always up- or downscale it a bit to fit your needs.

There's a little hole for the LED strip to go in.

The LED lightbox is made up of two parts, which makes putting it together a breeze. The cover should fit snugly so it won't fall off but still be easy to remove when necessary.

Printed on a Bambu Lab X1C on a Textured PEI Plate (which I would also recommend you doing).
