DIY Filament Dryer for 3D Printers Using Inexpensive Plastic Cereal Storage Boxes

These are the least expensive, clear, airtight containers that can be used to store and dispense filament.

WHERE TO BUY:

Cereal Containers Storage Set (4L / 135.2oz), 6PCS Airtight Food Storage Containers with Lids

MOISTURE METER (Hygrometer)

At first I started using digital hygrometers that display moisture and temp. The problem is that the batteries only last a year or so, and then your left with replacing a lot of batteries. Eventually you get battery replacement fatigue and stop replacing the batteries.
