In this video lesson we describe how to print designs from Sketchup on a 3D printer. Key thing is you need to go to the sketchup Extension Warehouse, under the window tab in scketchup. Then you need to search for and install the .STL Export extension. With this extension, you can export your design file as an .stl file. Then you can load the .stl file into your slicer software to generate the gcode for the printer. I found that it is very straightforward to go from sketchup to the 3D printer.
