interlocking ideas for openscad

[curious aardvark]

it is a cylinder :-) just an 8 sided one.

That's pretty much exactly what i did - mine was just laid out better lol

// mini itx case
$fn=100;
difference() {
union(){
cube([20,20,1]);
cube([20,1,5]);
cube([1,20,5]);
translate([21,10,0]) cylinder(d=5,h=1);
} // end union
translate([10,19,0]) cylinder(d=5.4,h=1);
} // end diff

why 2% of design effort ?

All i have to do is size it properly and add a hole with raised support.
