@LexYeen That said - as it's an issue I've been poking at for the last 11 months or so with The Folly, what do you want to produce? Maquettes? Parts? Paperclips? Different CAD lends itself to different sorts of work. And then the slicer software converts the models into something the printer can make, with varying degrees of success...
@LexYeen Oooh! Ok, then Open SCAD is probably a good start. It does everything through code and primatives - make a sphere, draw a box, extrude, rotate, join, cut, etc - which totally lends itself to making repeating geometric objects of repeating design, like cogs and gears and hubs and stuff. Making lugs out of cylinders, hollowing them out, joining to other cylinders and so forth - excellent use case. n.n
