Thanks for that.
Are those plans for modern CNC machines or hand tools or both? Are they up to date with technology?
I haven't looked through all of HH's links, but the ones I looked at, I didn't see toolpaths.
In a very simple, TL;DR, I'm typing on a tablet explination:
3D printing: you will generally download a particular file called an ".stl". This is a 3 dimensional mesh file. It basically makes the outside shell of your object with a bunch of triangles. You will import that into a slicer program on your computer, configure the slicer with your machine and materials specifics (temp, print speed, how many walls you want, infill, nozzle size, and a million other possibilities) and that program will spit out the gcode that you load into your printer and it actually goes brrrt.
CNC machining: is similar, in that you will download a 3d object (in HH's links they appear to be Solidworks models) and load that model into another program. For machining you will need a Computer Aided Machining (CAM) package. You will tell that program the variables you are using. (Tool diameter, tool offset, spindle speed, movement speed, how much to cut per pass, and a bunch of other variables) and it will spit out the .gcode* that tells your mill where to move. This is referred to as a "toolpath".
In general you won't see finished toolpaths in these downloads, because they are tailored to a specific machine set up and material you used, and gcode itself is extremely clunky to write and edit. So you get the objects with the design done, and do your own slicing or toolpath generation.
The Ghostgunner home CNC is the notable exception in that it ships with it's own toolpaths, but it is also very limited in what it can do.
So you will download the 3D files for what you want, but it will require a little work and knowledge to get them on your machine and cut/built.
*it should be noted that gcode comes in several flavors, and while both types of machines use gcode, the files are NOT interchangeable. Your gcode flavor depends on your motion controller's firmware.
