I have a steel rod, attached to the ceiling in the darkroom. On it are about 25 clips for attaching the film and then I have weighted clips for the bottom of the film. I leave them to dry overnight and the room is fairly dust-free.
IKEA used to make a kitchen cabinet - a bit more than 6ft tall - about 18 inches wide and 18" wide. You could get a sliding rack for the top and attach the clips to that and just pull it out to remove the film.
I built one for another darkroom, cut a hole in the top and stuck an airfilter (from an older model Civic at the top) - sealed top of it, Then I stuck a small computer cooling fan in the bottom - air would be drawn down over the film and as there was no heat, just airflow, it would dry film in about 2-3 hours. Now I dont need to have the film ready in that time - overnight is fine.
