+            Experimenting with the OpenSCAD language, <a href="https://www.sol75.com/">SOL75</a>
+            offers an online customizer where the inputs are the desired performances of a component.
+            The software then finds a suitable value for each of the component parameters, modifying
+            its geometry to make it compliant with the requested performances.
+            This allows for example to directly specify the maximum mass for a part, or the mechanical
+            load it shall support.
+        </p>
+        <p>
+            The project is geared toward functional mechanical parts, with built-in support for common 
+            printing materials, customizable printer configurations and dynamically generated documentation 
+            based on component requirements. You can have a look at <a href="https://www.sol75.com/">SOL75 landing page</a>
