Ender 3 Vent Ring 2-remix

Remix of Thing https://www.thingiverse.com/thing:3343456 with the corners of the mount area knocked down a little in width. A comment on the original thing mentioned this hitting clips in the front right corner so maybe this will help a little.

I used OpenSCAD to import the STL, positioned 2 cylinders and took the difference from the original STL.

OpenSCAD file contents:

translate([0,-35,-1.1]) // center the new part and move to z=0
    difference() {
        import("V-Ring_2.stl");
        `#`translate([-7,8.5,0]) rotate([0,90,0])
            cylinder(r=11,h=15);
        `#`translate([-5.5,61,.5]) rotate([0,90,0])
            cylinder(r=12,h=10);
    }
