I repurposed the lightning element of an Ikea Solvinden lantern to fit a custom lamp shade. The lamp was created with OpenScad with a ton of customization options :D Printed with yellow Prusament PETG

      That would be indeed interesting - goes onto my pile of things I want to do :D Thank you!

        I just printed this one 80mm tall. I need to fix the stringing:

        $fn = 10;

// small
/*
radius = 15;
height = 40;
thickness = 1;
*/

// how much can I scale this before thickness=1 fails?
// this one is a bit wobbly, probably near the practical limit.
radius = 15*2;
height = 40*2;
thickness = 1;

num_lines = 12;
rotation_angle = 180/num_lines*9;

module draw_line(i, rotation_angle) {
    angle = 360 * i / num_lines;
    bottom_x = radius * cos(angle);
    bottom_y = radius * sin(angle);
    top_x = radius * cos(angle + rotation_angle);
    top_y = radius * sin(angle + rotation_angle);
    
    hull() {
        translate([bottom_x, bottom_y, 0])
            linear_extrude(0.1) circle(d=thickness);
        translate([top_x, top_y, height])
            sphere(d=thickness);
    }
}

for(i = [0 : num_lines - 1]) {
    draw_line(i, rotation_angle);
    draw_line(i, -rotation_angle);
}

linear_extrude(0.6)
difference() {
  $fn = 50;
  circle(radius * 1.1);
  circle(radius / 1.1);
}
