Yeah, I know, that “Free” on the end of that title looks a little cheezy, LOL.  What can I say, just trying to get the word out about an important new feature in our G-Wizard Calculator.  Believe it or not, it isn’t the Bolt Circle Calculator that’s important, although it’s cool.  It’s that we’re going…

3D Printers are cool–they’re very fun to play with.  But they have some drawbacks too.  They’re slow, the quality of the surface finish on parts you print often requires a lot of extra work to smooth out, they can be finicky unless tuned up, and they’re not incredibly cheap either for all that.
