A pair which I am most of the way through: _Make: Geometry: Learn by coding, 3D printing and building_ https://www.goodreads.com/en/book/show/58059196 https://www.goodreads.com/en/book/show/58059196 and _Make: Calculus: Build models to learn, visualize, and explore_ https://www.goodreads.com/book/show/61739368-make https://www.goodreads.com/book/show/61739368-make I'd really like to find a similar book on conic sections --- my next major project seems to need them, and when I tried to solve it using trigonometry alone, I wound up 7 or 8 levels deep in triangles and wasn't much more than half-way to where I needed to be.
