This is designed to use the least amount of filament and have a quick print while being very functional.

This can be great for storing your filament and also keeping your filament in a dry box while using it.

You'll need to purchase the following: (Amazon links for all items needed)
Skroam 4PCS Cereal Containers Storage

You can use the following Hygrometer or similar in size
6-Pack Mini Hygrometer Indoor Humidity Meter

3/8 inch drill bit. You might already have one, but here is a link. I didn't buy this because I already own one.

Silica gel beads. Use which ever you like. The ones I have used and like are:
Dry & Dry" [1 Quart Premium Orange Indicating Silica Gel Desiccant Beads (Orange to Green)

and 
Wisesorb Silica Gel 2 LBS, Indicating Silica Beads (Blue to Pink)

It will be about $1 or less to print 1 unit.

Steps:

• Place the hygrometer on the front of the unit as shown in the pictures. press from the front and snap it in.
• Place the unit insert in the bottom of the food container. This will be a tight fit, so reach in and press down in all corners. The unit will not fall out now even if turned upside down and knocked around.
• Use a 3/8inch drill to put a hole in the lid of the container.
• Place the Tube bolt in that hole and secure with the nut.
• Place the tube through the tube bolt.
• Fill the container with your desired amount of silica gels.
• Place your filament in the container and pull filament through the tube.

I added a cap to cover over the tube if storing for a while.

I printed with PLA and PETG.
If printing with PETG the nut can be hard to screw all the way. You may require pliers to fully tighten.
If printing with PLA, I've had no issues.

The silica gel beads can easily be poured out when you need to recharge/dry them.
