RWG Filament Cooler modified with OpenSCAD (DOES NOT WORK WELL)

This is a modification of the RWG Filament cooler using OpenSCAD.
Thanks to Russ Gries for the cooler design.
As I can not print vertically, I decided to modify the cooler to print horizontally in 2 parts.
I modified this part for Lyman Filament Extruder v5 that I am customizing for my build.
I used slic3r to split the parts into two, hence the adjustments.
After downloading the scad files, you will have to modify the location of the STL files to edit them.
I added 3mm holes to screw this
