customizable multi color vase

thingiverse

So yesterday my friend showed me this cool thing prusa is doing http://prusaprinters.org/original-prusa-i3-mk2-multi-material-upgrade-release/ Since there aren't many designs out there that need more than 2 extrudes I figured I'd make something that does Also, it looks like trash in customizer and I'm not sure why but would love to hear what you think is causing it I also don't know why multi file output isn't working or really why any of the bugs are happening at this point This stuff just hates me, I swear it works beautifully on desktop without any problems like this so you'll have to make them one by one for now Here's how I designed it: So here is the code: //BEGIN CUSTOMIZER VARIABLES /*[Vase Settings]*/ height = 150; radi = 50; I like counter clockwise twists personally. num_of_twists = -2; need to have this times num_of_colors >3 times_each_color_appears = 2; thickness = 4; /*[Color Settings]*/ need to have this times times_each_color_appears >3, I realize 8 color support is overkill for now but still fun to consider num_of_colors = 4;//[2:8] pick what colors appear in the CUSTOMIZER colors = [[0,0,1],[0,1,0],[1,0,0],[1,1,0],[0,1,1],[1,0,1],[0,0,0]] ; /*[display]*/ 4 displays all 0-3 displays lone parts part = 4;//[0:4] //END CUSTOMIZER VARIABLES module vase_segment() { angle = 360/(times_each_color_appears*num_of_colors); difference() { for(i=[1:times_each_color_appears]) { rotate([0,0,360/times_each_color_appears*i]) linear_extrude(height=height, twist = num_of_twists*360, convexity = 10) { intersection(){ circle(radi, $fn=25); polygon(radi*[[0,0],[0,1],2*[sin(angle/2),cos(angle/2)], [sin(angle),cos(angle)]]); } } } translate([0,0,thickness]) cylinder(r=radi-thickness/2, height); } difference() { if(part ==4) for(i=[0:num_of_colors-1]) { color(colors[i]) rotate([0,0,360/(num_of_colors*times_each_color_appears)*i]) vase_segment(); } else color(colors[part]) rotate([0,0,360/num_of_colors*part]) vase_segment(); } I'll explain more in the morning and probably clean it up but more or less with a bit of geometry it does stuff. That 2*[sin(angle/2),cos(angle/2)], for the polygon came from what would the hypotenuse be relative to radi if there were only 3 segments to make.
