Contributions summary:Jack contributed to the development of Cura, a 3D printer slicing GUI. Their work involved implementing features such as adding line thickness to layer views, representing layer thickness as an array within the code, and adapting the layer shader to use a custom attribute for line dimensions, instead of utilizing UV coordinates. These changes involved modifications across several files related to layer data handling, shader code, and processing of sliced layers.
