This is a simple tray system that fits the eSun eBox Lite.
The tray fits right into the vent at the back of the eBox and has angled walls to allow the air to flow through the beads and out the vents in the lid. This drys the beads quite quickly, even on the PLA dryer setting (I've tried PETG setting with my PLA print and no deformation was seen).
I don't have exact times for how long to dry, but the built in hygrometer will start to rise as the beads release the moisture and then fall again. The hygrometer I used will go down to 10-12% and then the beads are restored to their original orange.
I tried placing desiccant containers (spool ones) into the eBox and found that only the ones near the vent would dry. This tray makes sure the air flow is being utilized in taking the moisture away.
After drying, the beads are easily poored out of the tray via one of the for corners. I use a simple funnel to easily poor into the original bottle or into any drink bottle.
Note: The beads shouldn't be filled to the top of the tray. The hygrometer sits into the tray and the lid should sit flush for best drying.
Note: I prop the eBox lid open a few millimeters when drying. Not sure if it's needed but wanted the moist air to have a plate to escape.
