I have made a small extension for the EIBOS Polyphemus so that I can also use the filament dryer to dry silicate beads in boxes, things or anything else.
I hope it is also useful for you!

You can simply use the stands for the 2nd floor as they are, or you can print out the optional air distributors. 
These can only be pressed into the top. Simply turn them slightly until they engage in the guide and then press them in until they resist. 

Many thanks to [https://makerworld.com/en/@bobbyg2018](https://makerworld.com/en/@bobbyg2018) for the inspiration. I chose his shelves as a starting point and modified them.
