CAD

I'm still looking into CAD and 3D printing, neither of which I have done before in the current century (though I did develop and use some in the last century!). My first VERY simple design was printed for me by a friend earlier in the week, and I'm now getting slightly more ambitious. I've already started making a list of a few simple things I need to design and print, but investing in a 3D printer is still something I have to think about, as I'm not sure that I can justify the expense (and find the money), given that it would not not all that much use, and I already have so many other things to do.
