The Ultimate DryBox Filament Feeding System

I looked at a lot of filament feeding systems and storage systems and some feeding storage systems, but they just didn't fit my needs. After a number of trials and errors, This system is working for me and I thought I would share it. If you do make this, please share photos of your "Ultimate Drybox". I would love to see it.

Airtight Clear Plastic Cover

I used a vacuum bag to make a humidity controlled area.
NOTE: I'm not 100% happy with the vacuum bag because it rips pretty easy but I am using it successfully.
NOTE: I used electrical tape everywhere I was going to have to make a hole in it. It made the hole stronger and airtight. (I taped the area and screwed the hole into it.)
NOTE: Where I couldn't screw into a stud, I used drywall anchors.

Regular Shelf

I put up a regular shelf at the top to give the plastic cover some open volume to work in - very helpful. It also gives me a place to put filament I haven't taken out of the original wrapper.
NOTE: The shelf itself goes inside the plastic cover.

Remember when you are buying these, you will need two for the shelf and two for every row of spools. I used 6 in my setup.
Shelf: 24"X 10"

- Probably cheaper at Walmart, Lowes or Home Depot. While you are there, you may want to get some of the other items.

Steel Rod

I used a hardened steel rod to hold the spools. This is the only item I got from ebay. It would have taken too long to get it from Amazon.
NOTE: Using the ebay user I listed below, I received the rod a day early and it was exactly what I needed.

Spool Hubs

This spool adapter ("spool hub") adapts spools to use standard spinner/skateboard bearings. If you would like me to make a custom size spool hub, please request. I just need the inner size in mm to the hundreth: xx.xx mm

NOTE: These are designed to be a tight fit. Bearings are easier to put in from the smaller ring side. This is a one-size-fits-most for 1 kg spools and I have only tested AIO 500g spools. For what they fit, they work awesome (maybe too good - sometimes they overspool - no big issue). It only takes 9g for a set of 2 X 500g spool hubs and 12 grams for a set of 2 X 1kg spool hubs.
NOTE: I bought more bearings than I needed, but it was just a little more money for a lot more bearings. I can just make some spinners for friends and family with the extras.

Shelf Brackets / Rod Holder

To save time and filament, I used shelf brackets to hold the rod with a 3d printed rod holder.
NOTE: The bracket is wide and has two side holes if you want to use a bracket in the middle breaking up the filament rack into multiple segments making it easier to change out filaments. This would come in handy if you have to replace one or two colors pretty regularly. In this case you would want to order the steel rods in those lengths unless you had a way to cut the steel rods.

Shelf Brackets: Use the same as mentioned previously

Filament Feeder

I used a previously made filament feeder bolt and nut to get the filament out of the drybox. I added a special nut that you could connect to the filament feeder and screw into the wall to give the feeder the needed stability when the filament is being pulled throught the tube.
NOTE: I had to superglue the tube into the filament screw to secure the connection.

Humidity Control

I added a holder for a humidity meter that would be easy to access the battery compartment, get good readings and be able to see side-by-side the outside measurments. I am using a rechargable dehumidifier.
