From video description by Steve:
I thought some of you might be interested in seeing a high level overview of the tools I've been using most often for 3D design and printing.
Modeling in Solidworks and exporting .stl files. Loading an .stl file into Kisslicer, showing basic slicer settings and saving the resulting G-Code. Then using Repetier-Host for local printing and/or printing via wifi to a 3D printer located in another room of the house using my LG G2 smartphone as the printer controller with GCode Simulator and Printer software.
