3D CAD programs??

Fusion360 all the way. I use it for day to day repairs and large integrated jobs. Think there's a free tier for personal use.

I haven't tried anything yet except thingyverse. When you find a program that is easy to use let us all know.

Ok, this is a "What do you use question" if you want to design 'something' for 3d printing - as in the initial CAD part of the process.

I downloaded Freecad and not sure I like that at all, am playing with RS's Design Spark Mechanic at the  moment (free version) but would rather not use it once I have my Noise Canceller box reworked and out of it (all the talking back to home and spying on one's work is annoying).
