Of the 8 items on the accessories page, I saw nothing of critical interest. The library printer is still running fine on the original nozzle, although the PEI bed was worn out after about a year. We learned to move the print from the center and place it randomly on the bed each time! It's easy to remove the old PEI sheet (Dry Ice) but it's a bear to get the adhesive layer off cleanly. You may not have to deal with that, with the new pop-off bed system.
