Vampire holder

thingiverse

When I was a senior high school student, I used clay to make a vampire holder in an art class. After grading, the teacher took away my work. I thought he would give it back to me after firing. But I never saw my work again XD I don't know why I remembered the vampire holder a few days ago. Then, I tried to create it in OpenSCAD. It's also a demonstration of how to use [my library](https://github.com/JustinSDK/dotSCAD). The feet are created by `shape_ellipse` and `ellipse_extrude`. The body is generated by `rounded_extrude` and `hollow_out`. The sunglasses are made by `bend`. The cloak is modeled by `bezier_surface` and `function_grapher`. If you download and use my library locally, here is the code: include <shape_ellipse.scad>; include <ellipse_extrude.scad>; include <rounded_extrude.scad>; include <hollow_out.scad>; include <bend.scad>; include <bezier_curve.scad>; include <bezier_surface.scad>; include <function_grapher.scad>; holder_height = 80; holder_round_r = 5; feet_height = 15; module vampire_holder() { $fn = 48; module feet() { module foot() { ellipse_extrude(semi_minor_axis = feet_height) polygon(shape_ellipse(axes = [20, 30])); } translate([25, 0, 0]) foot(); translate([-25, 0, 0]) foot(); } module holder() { radius = 30; rounded_extrude(radius * 2, round_r = holder_round_r) circle(radius); translate([0, 0, holder_round_r]) linear_extrude(holder_height) hollow_out(shell_thickness = 4) circle(30 + 5); } module sun_glasses() { glasses_path = [[0, 5], [40, 10], , [15, -10], [0, -5]]; thickness = 4; rotate(-45) bend(size = [80, 20, thickness], angle = 90) translate([40, 10, 0]) linear_extrude(thickness) union() { polygon(glasses_path); mirror([1, 0, 0]) polygon(glasses_path); } } module cloak() { t_step = 0.05; thickness = 4; ctrl_pts = [ [[10, 0, -20], [60, 0, 55], [90, 0, 60], [150, 0, -20]], [[85, 50, -25], [55, 40, 10], [115, 30, 35], [80, 50, -40]], [[25, 50, 100], [60, 70, 70], [90, 70, 70], [150, 60, 70]], [[0, 70, 100], [30, 80, 90], [90, 80, 90], [150, 80, 90]] ]; g = bezier_surface(t_step, ctrl_pts); rotate([-90, 0, 0]) function_grapher(g, thickness, style = "HULL_FACES", $fn = 3); } color("black") feet(); color("white") translate([0, 0, feet_height - holder_round_r]) holder(); color("black") translate([0, 12.5, holder_height * 5 / 6]) sun_glasses(); color("gray") translate([ -80, holder_round_r + 0.5, holder_height + feet_height - holder_round_r] ) cloak(); } vampire_holder();
