Things

We should have a thread full of things we're 3d printing.
Here's an air manifold I'm printing now for growing algae:

module Connector(id=4,od=6,l=30){
    rotate([-90,0,0]){
    difference(){
    union() {
        cylinder(l,od,od/2,center=true);
        sphere(od,center=true);
    }
    cylinder(l+2,id,center=true);
}
}}

module Manifold(count=8, connectorid=3, connectorod=4,wallthickness=2) {
    spacing = connectorod;
    loa=(spacing+connectorod)*2*count+spacing*2;
    boxw=(connectorid*count)/2;
    connectorlen=20;
    translate([0,boxw/2,0]){
    difference() {
    union() {
        cube([loa,boxw,boxw],center=true);
        for(i=[1:count]){
            translate([loa/2-(loa/count)*(i-0.5),connectorlen/2+boxw/2-wallthickness*2,0]){
                Connector(connectorid,connectorod,connectorlen);
            }
        }
    }
    cube([loa-wallthickness,boxw-wallthickness,boxw-wallthickness],center=true);
    }
}
}
Manifold();

Spirulina?

Is that OpenSCAD?

Chlorella, it's very tolerant. All my spirulina died. You don't need "nutrients." Just piss in a bottle when you're sober and haven't had coffee in a while, that will last you like all year.
>>3
Yes.

Do you grow algae for food?

No. I'm experimenting with making fuel and 3d printer filament with it.
