$150 cost and free cad files? for the needed? What a joke.
It reminds me of the Americans spending thousands to develop a pen for Nasa in space.
Some people took a pencil to space.
Here is a project from 2015 already invented without the need of cad files and uses only local materials: https://www.warkawater.org/
Pencils are dangerous in space—they can cause fires. Also, the “space pens” were not developed with taxpayer money but instead by a private company, and they actually saved NASA a lot as they bought them for dollars instead of hundreds or thousands as they did with pencils.
I'm thinking of using godot for the GUI on a decently complex Windows application. I'm concerned that Microsoft is no longer interested in desktop applications and I don't want to embark on something that has no long term future.
