Actually starting to like using it now that I can relate to just how big 4mm is. Been playing with 3D printers and of course had to take the step into 3D CAD. I found a free CAD program from Allied Electronics called Design Spark. When I first started using it everything was metric and I couldn't figure out how to change it so I just started drawing in mm. Of course every bolt Nut and part on a 3D printer is metric. Have a pretty nice set of calipers that does both metric and inches which really helps.
Anyway now that I have a pretty good handle on the metric system I'll probably never go back to inches, it really is a whole lot easier to work with.
