Time to invest the comparable amount of money in FOSS alternatives? FreeCAD, LibreCAD, BRL-CAD, and so on.
FreeCAD is the closest, but unlike the Eagle vs Kicad comparison, it's miles behind Inventor and Solid works. I just bought a lifetime license for Alibre CAD, it's for profit closed source but much more usable. FreeCAD needs a benefactor like CERN for KiCAD to bring it up to speed.
Just the other day I cloned one of these[1] in freecad using the image importing and scaling, quickly made a trace, added a pad and some chamfers, and had it on the 3d printer in about 25 minutes.
I'd love if FreeCAD got a benefactor like you mention.
