Drying agent trays for Polybox I & II

These trays can be filled with desiccant (silica gel) and used in both Polybox I and II. This makes it possible to use both pouches and loose desiccant and remove it easily from the Polybox.

The original cover plates remain in use to cover the tray.

The trays are printed in vase mode with a layer hight of 0.25 

I have also attached the FreeCad Files (.FCstd), so you can customise the trays to your own preference.

Note that there are two types, one for the glade side and one for the side with the hygrometer.
