What tool do u use for 3d modeling?
I use fusion360. It’s a controvertial choice due the annoying license but still free for private non commercial use. The parametric modelling brings a huge efficiency advantage, I modeled all these stuff with fusion, modeling can be as fast as capturing measures
If you start with it, you need first to watch a lot of youtube videos before you even touch it to have a good grasp of the concept, the rest is practice, I also have a 3d mouse, that feels nice but you can be almost as fast without.
