Drink Coaster

I was digging through OpenSCAD documentation and decided to tackle something using the minkowski() command. Luckily, this turned out to be a success. (Also, let me know if you spot the customizer option; when I uploaded the file, it didn't show up.) My next project involves experimenting with the hull() command. Also, the image isn't quite working yet, but I hope to get it functioning soon. How I Created This minkowski explained minkowski(){ cylinder(h = .0000000001, r = diameter_of_coaster/2 - height_of_coaster,$fn = resolution, center=true); sphere(height_of_coaster/2, $fn=resolution, center=true); } So how (I think) minkowski works is that it tries to combine the items inside it, so in this case, it attempts to create a cylinder with a sphere revolved around its outside. It also adds the heights of the two together, which is why the cylinder height is set to an extremely small number. (If it's 0, no cylinder is made, so you make it very close to zero.) It also adds the sphere's diameter to each side of the cylinder, that's why it has - the diameter of the sphere when making the radius of the cylinder.
