if __name__ == '__main__':
    # Quick and dirty argument parsing
    if len(sys.argv) != 2:
        print 'Usage: %s [ZIPFILE]' % sys.argv[0]
        sys.exit(-1)

    eui_zipfile = sys.argv[1]

    try:
        tempdir = tempfile.mkdtemp()
        with zipfile.ZipFile(sys.argv[1], 'r') as zf: 
            zf.extractall(tempdir)

        srcdir = os.path.join(tempdir, EUI_DIR)
        dstdir = os.path.join(os.path.expanduser(DLC_DIR), EUI_DIR.lower())
        shutil.copytree(srcdir, dstdir)

        os.chdir(dstdir)
        for root, dirnames, filenames in os.walk('.', topdown=False):
            for filename in dirnames + filenames:
                orig = os.path.join(root, filename)
                new = orig.lower()
                try:
                    os.renames(orig, new)
                except:
                    pass

    finally:
        if tempdir:
            shutil.rmtree(tempdir)

I'm not sure if this is the right place for this, but a much easier way to do this would just unzip the original EUI zip using 'unzip -LL eui_zip.zip' which automatically forces conversion of every directory and filename to lowercase.

Thanks for the comment Mfdas, noted in comments. Definitely a better way to do it, this was discussed in the reddit thread as well.

This also seems to work (after extracting):

convmv --lower -r -f UTF-8 --notest UI_bc1
