This tray fits inside a food dehydrator shelf/tray to hold silica gel desiccant beads while still allowing the warm air to pass through.

It must be sliced properly: 1.2mm wall thickness, no top or bottom thickness/layers, open infill style, right infill percentage. I used Triangles for an Infill Pattern, with an Infill Line Distance in Cura of 2.4mm, which resulted in an Infill Percentage of 50%. You want the grid to be as open as possible without letting the beads fall through. Don't use Cubic or Gyroid or any other three-dimensional pattern, since they can result in closed cells.

To add strength in the absence of top and bottom, I use the Cura features Connect Infill Lines, and Alternate Extra Wall.

This is designed to fit the Commercial Chef CCD100W6 (https://www.amazon.com/dp/B075ZB3V9S/ref=cm_sw_su_dp) which apparently is the successor to the Westinghouse WFD100W.

Although everything I read says to refresh desiccant at 80 or 110 or 150 degrees Celsius, obviously the tray printed in PLA won't stand up to that. So I set it at 113 Fahrenheit (45 C) and my beads were dry in 2-3 hours. (I have the color-changing kind so I can tell.)

When dumping the desiccant out of the tray after drying, make sure to cover the center hole with your hand so the beads don't fall through the hole.
