+- [blender](https://blender.org) is a very powerfull 3D modelling software. All parts of the cube are modelled with blender. You can edit the blender files and change details on the design. The blender-design files can than be exported to STL-format, a common 3D-file format used for 3D-printing.
+- [prusa-slic3r](https://www.prusa3d.com). This is the slicer software for 3D-Printers from the manufacturer Prusa. This programm is used to convert the STL-files to printerspecific gcode-files.
+
+The subfolder `files/` containes the blender files, the corresponging STL-files and the already sliced gcodes for Prusa-MK3S printer.
