Printed with 0 top and bottom layers, with a 40% grid infill. This is a really useful trick for creating a thru mesh on parts. Printed in PETG on the textured pei plate with some glue stick to help with both adhesion and release when finished. These fit the nesco dehydrator trays. They do fit up into the next level tray, but I use trays that I've removed the mesh as a spacer. These “open” trays can also be stacked to be able to put a filament spool in for drying, so they do work multipurpose.
