Nice idea - build a disaster !!

To glue the track and not to drill I liked. They can be easily adapted to the respective door width. The adhesive strip that allows the strip is solidified looks strong and should hold for some time.
But now to the remaining structure:
I am technically talented but the grid did not want to keep in the track, even after repeated attempts. Have it now abandoned and will someone draw assistance. Impossible to secure the part so !!
