SMART Polydryer

Make your Polydryer SMART

Add a Smart humidity and temperature sensor to your Polydryer box to get notifications once your humidity rises above an acceptable level (subject to setting it up in your hub/app/Home Assistant - whatever you want to use for the SMART sensor monitoring).

I remixed Scott's @ScottWolfs PolyDryer/SnapDryer the desiccant basket from:

I added a holder for the Xiaomi Mi Temperature & Humidity Monitor 2
I added extra holes at the top of the back of the basket to increase airflow
The original plastic window on the desiccant basket fit perfectly.

It is recommended to print the basket with the filament with higher temperature resistance than the filament you will be drying in the Polydryer.

Warning:

I don't recommend it for narrow spools like the one on the last two photos. It is still usable, but due to the spool touching the holder there will be a resistance in dispensing the filament from the Polydryer.
