cura - 4.8-4 main

Cura converts digital 3D models (.stl and other formats) into printing
instructions (G-code) for your 3D printer. It cuts the model into horizontal
slices (layers), generates toolpaths to fill them and calculates the amount of
material to be extruded.
.
Cura is easy to use for novices and provides over 200 settings to adjust
for the expert. It can output G-Code for several series of 3D printers,
most notably the Ultimaker.
