Openscad christmas tree

youmagine

I aimed to devise a mathematical equation that would generate a tree shape. The scad code I came up with is purely intuitive; no doubt someone more skilled could calculate some coefficients and transform this into a single, iterative formula. This design prints best on a printer using spiral vase mode. I incorporated a cylinder so there's something to hang the tree from; unfortunately, it only works within a limited range of sizes. If you're an expert at editing G-code, you might be able to add lines like G92 Z0 E0 and G91 Z25 E20 to the end of your print to make the hotend move straight up while extruding a small string of filament.
