Cover art of Dark Side of the Moon. Iconic, etc.
All - 0.1 mm layer thickness
Base - Black, change to white at 1.5 mm.
Red, Orange, Yellow, Green, Blue, Violet, Octarine - Use the appropriate color, straightforward.
Hanger_flat - used for wall hanging, color up to you. Align the hanger to the rectangle on the back of the base to center.
Assemble the color rays in the slot using super glue. Going in order from top to bottom seemed to work best, sliding in the last piece.
Use the Hanger_flat if you want to hang it on the wall, or stick a magnet on the back for fridge display.
