Hexagon LED Litophane Lamp

I modeled this LED litophane lamp in Blender 3d.
For lighting i used a 5v USB LED Strip.
The litophane was made on https://3dp.rocks/lithophane/. I used this settings:

resolution of uploaded image: 3000x2000 (with 3mm black border)
image settings: positiv Image
model settings:
maximum size - 130
vector per pixel - 9

I printed securly with support from ground, maybe it is possible to print without support.
