Parametric OpenJSCAD vase/shade/case script

thingiverse

Parametric OpenJSCAD scripted vase available at https://openjscad.org/ enables users to generate vases, lampshades, and cases for travel or storage of small parts. The vase outline is calculated by summing a sine wave with parameters for number of z-waves and z-waves phase, along with a parabola with parameters d0, d1, and d2. Wave amplitude is defined by another parabolic function with parameters ah0, ah1, and ah2. Circular waves are produced using a parabolic amplitude with parameters ar0, ar1, and ar2, combined with a sine wave with parameter number of radial waves. The rotation angle is also controlled by a parabola with parameters wr0, wr1, and wr2. All parabolic functions use the z coordinate as their argument. A calculation tool helps users define script parameters at https://goo.gl/RMFUcx (wait for diagram). Vase.jscad and twisted_case.jscad files have different parameter sets. The author uses SBS filament and spiral vase mode, suggesting a bottom solid infill of 3 for vases and cases, while lamp shades require no top or bottom solid infill. For optimal transparency, the author recommends using a 1.2mm nozzle, 0.4mm layer height, 1.8 extruder multiplier, and low speed (5/6mm/sec on their Prusa).
