all .stl files :
Step 1: Description
Hakking IKEA RIBBA 230mm x 230mm to make a lithophane frame with 12V led strip lighting
Step 2: Conversion of Image to Lithophane
1) Picture must be cropped to 1x1 proportion to fit the IKEA frame opening 116x116mm
2) Model settings (see picture) :
a. Maximum size: 126mm (116mm + 2x5mm border)

c. Border: 5mm
d. Thinnest layer: 0,8mm

g. Curve: 0
Step 3: 3D Printed Parts and Assembling
Designed with fusion360 , sliced with Cura and printed on Creality CR10S
1) Front frame : 231 x 231mm, thickness: 10mm,
2) Centering frame with opening for the base of the lithophane,
3) Led lighting support frame for alu V profile, with guides for the wiring system,
4) Lithophane of my grandchildren, but for the example I used the picture : the girl with the pearl earing (https://en.wikipedia.org/wiki/Girl_with_a_Pearl_Earring )and she had a cat .
Step 4: Print Settings
I used white PLA 1,75mm from 3Donline (https://3donline.be/ ) for all printed parts
1) Lithophane : 0.1 layer heigth with a 0.4mm nozzle, 100%infill,
2) All other parts were printed at 0.2mm layer height with 20% infill , infill pattern gyroid,
3) All parts can be assembled by pressfitting them without any glue,
4) The total print time for all parts was about 40 hours , lithophane printing is very slow (20hours).
