Autodesk® AutoCAD® programs and MatterHackers® MatterControl® programs were used to prepare the project. Tools such as digital caliper, HP 50g calculator, among others, were also used. For printing, a RepRap printer with processing using a dedicated Arduino® board and Marlin 1.1.x interface / software was used. ESUN PLA Premium 1.75mm filament on a 1kg spool in black was used to make the pieces. The print settings were made all from parameters set in MatterControl® and export of the .stl and .g-code files in the corresponding file folders.
