I create a modular lightbox for 10x7.5cm lithophanes. With this model you can create any lithophane collage.

To hold the lithophanes I made 2 possible mechanisms:

• With magnets (5x2mm). It makes possible change pictures or picture position.
• Without magnets, to glue. (Also tolerence should be enough to not use glue, but not as effective as magnets)

There are two different models.

• Row:
  • You will need x2 row_lateral
  • As many row_center as you wish. There is also an option with a hole in case you want to connect leds externally.
  • As many frames as you need (with or without magnets)
  • x2 connectors per connection between pieces.

• Matrix: Scalable at any size from 2x2. In an example of 3x3 you will need:
  • x2 Matrix_Corner_Left (option available with hole)
  • x2 Matrix_Corner_Right
  • x2 Matrix_Frame_horizontal (option available with hole)
  • x2 Matrix_Frame_Vertical
  • x1 Matrix_Centre
  • x9 frame (with our without magnets)
  • x24 connectors

For Bambulab, Check my projects for all pieces, 3x1 and 3x3 lightbox, and lithophane profile here:  [https://makerworld.com/en/models/422779#profileId-325890](https://makerworld.com/en/models/422779#profileId-325890)

For assembly:

• Locate all the box pieces to to have clear view how to glue them.
• Glue all the box pieces using the connectors.
• Glue magnets if used. Take care that magnets are added correctly so frame and box do not repel.
• Optional glue lithophane to the frame.
• Add any led you want.

To create the lithophanes I use [https://itslitho.com/.](https://itslitho.com/.) . Apply a Black&white filter to the picture before upload for better result. You have to use the following parameters:

It's important to have the crop option enabled in case the picture have different aspect ratio the application will take a crop with the correct ratio to fit the model.

For Lithophane printing I recommend, printing vertically, 0.12mm layer height, 6 perimeters and brim. 

I suppose it can be scaled to use bigger lithophanes, but i havent tried it.

I hope you enjoy it ;)
