I worked a lot with SolidWorks, Cinema 4D and such to get quality 3D results. But I try to use as much as possible all the amazing free alternatives! I’m a big fan of tinkercad. I print and scan things in 3D almost every day and I love to use CNC-machines. I know basic electronics, can play around with easy Arduino-code and I get simple html and gcode to work… This year, I got hocked up on Rhino/Grashopper for a more generative way of designing.
