I wanted to maximise the efficiency of the desiccant in a closed cabinet, so I designed that tray.

Please use the profile provided to ensure the tray is printed with a 2D honeycomb pattern.

Out of the 5 trays I printed, I had a first layer issue once because of the honeycomb on the first layer. The part was still usable, as it recovered the pattern in the following layers - I didn't use glue. I would recommend to use glue or a slower print speed if you have issue.
