I'm formatting a cover design in LaTeX. The cover has pages of 145×210mm which includes 3mm margin. The side should be 13.93mm wide and the bleed is 3mm. This gives me the following code, which declares three minipages: one for the back of the book, one for the side, and one for the front.
\documentclass[paper=303.93mm:210mm,10pt]{scrbook}
\usepackage[margin=0pt]{geometry}
\usepackage[center,cross,width=309.93mm,height=216mm]{crop}
\usepackage{lipsum}
\begin{document}%
\begin{minipage}{145mm}
\lipsum[0-5]
\end{minipage}%
\begin{minipage}{13.93mm}
Blah blah blah
\end{minipage}%
\begin{minipage}{145mm}
\lipsum[7-11]
\end{minipage}%
\end{document}
However, the first minipage is not aligned in the absolute top left, but a little bit to the right, so that the rightmost minipage ends up in the bleed area:

As you can see I already removed extra spaces inbetween as suggested here, but that didn't resolve the issue. I also already set the margins to 0 with geometry.
How can I align the minipage in the absolute top?
