I was inspired by the desiccant drying tray by PCHuDSoN but wanted to have a friction fit lid and a pour spout to easily dispense the refreshed desiccant back into their vessels.
I have designed this with a friction fit lid with 2 small lid catches to hold the lid on well. I also designed the spout to fit nicely with the small AMS dry pods I printed from Trey's Designs.
The print is designed to not need supports for the pour spout and prints well with PETG. There should be 0 top and bottom layers and 40% infill to allow air gaps to aid with drying of the desiccant beads. I have found that the beads dry faster with the lid off, so that does not need to be printed without the top and bottom layers.
I dried a half tray at 70C for about 6 hours with the Auxiliary and Chamber fans at 50% and the beads were back to bright orange. If you put the lid on, and plug the spout with your thumb, you can gently shake the tray a few time during drying to mix them up to speed drying.
