Hello i´m 46 years old and 5 years in with 3d printing. First i had to learn how a 3dprinter works second i have to learn how to slice my parts and to choose the right filament. The third step was to learn a CAD Programm i chose Fusion 360 and now i create my own stuff. Everthing i uploaded is printed by my self and tested so you can be sure to get good results if you print with my profiles. Hope you like my stuff.
