Personalize Your Lithophane Heart

Let’s start by personalizing your heart lithophane. The following link is a dedicated lithophane template for this heart box:


The image from the template is just an example, which you can replace.

Prepare your image

Let’s head over to the “Upload” tab and remove the current image. Then upload the image you want to use for your lithophane.

We recommend using an image where the focus point is centered. The heart shape cuts off some parts of your image.

Use the “Edit” tab of the tool to improve & optimize the lithophanes contrast when lighted. 

Model your Lithophane

The most important step in the “model” tab for the valentine’s heart box design is the minimum (Min Thick) and maximum thickness (Max Thick), which can be found under the “shape options”.

Depending on the filament you are going to use, this could be more optimized. In our store, you can filaments that work well with lithophanes, and suggested min/max thickness. 

The valentine’s lithophane box is compatible for 0.8-3.0mm thicknesses but should work until 4mm max thickness. So keep an eye on the max thickness.

However, the default settings are a perfect starting point.

It’s important to notice that there is no attribute required for this design.

Assemble your Heart Lithophane Box

When all parts are printed, you can assemble the Valentine’s Box together. 

To do this, you’ll need the following requirements:

led light

First of all, we recommend adding aluminum foil to the inside of the box.

The aluminum foil helps to reflect the light & avoids it from passing through the box.

Press the front of the heart in the foil to get an outline, and cut the shape out of the foil.

The second step is to install the led strip inside of the heart box.

You’ll need to insert the led strip through the hole. Then glue the socket to the valentine’s box.  

Then, you can install the led strip inside of the box. There is enough room between the lithophane and the back of the box to install two rounds of the led strip.

In the end, just cut the strip at the desired length.

Now, you can finalize the assembly.

Insert the lithophane, attach the cover, and slide the box on the stand. You can use some glue if the parts won’t stick. 

And it’s done, you’re ready to offer a personalized Valentine’s lithophane box.
