Great idea, but the hard-coded imperial units make this very difficult to use for most of the world. Also the plugin still appears to be extremely buggy and unfinished.
Considering the vast majority of money in the space going into QEC software, I'm so grateful for their work. Was so much easier than trying to everything from scratch with my limited CAD work over the years.
Then again, this is coming from a guy who had to call nearly every fastener supplier in a country in order to source a specific kind of countersunk UNC screw to fit foreign hardware he ordered. That still stings.
