I made this part for the Dahle 558 I have at my office.
you need to print 4 Middle parts to fit a Dahle 558 (1 print of each side + 4 middle parts = 145 cm)
I printer it with PETG. High Density (70% +-) is recommended, because more weight will hold better the paper under it.
Post-processing: you might want to add some glue to add stiffness.
