I'd love to know how much you make on your software... I imagine much more than the youtube ad revenue. This seems like a great formula for success- youtube content provides free advertising for your side project. EEVBlog does the same thing with his meters..

I did buy your gear template generator and tried it on the laser cutter. It's cheaper than the solidworks add-on that does the same thing :-)

Which is more successful, your plans or your software?
