A 3D printing dry box that is 90% printable it is designed to store the plastic while in use or not it uses 5 things that are relatively inexpensive parts that i will label you can easily source all these items that was the original point of this project an easy way to have a filament dry box with no drilling cutting no bs just print assemble and print away!

if your spool adapter is loose i find taking a small bit of painters tape and adding 1 or 3 layers of tape help the spool adapter get a snug fit but be careful not to get it too snug or you wont be able to remove them easily to swap spools of plastic

PTFE TUBING

PC4-M6 fittings - thread M6/3mm, inner diameter(blue end) 4mm, you only need 1 per box

3/4-Inch Precision Performance Ball Bearings 1-3/8-Inch outside diameter

a mini digital Thermometer hydrometer they are all pretty much the same size but for you hyper accurate people 1.89"W x 1.13"H

i personally suggest dry & dry orange indicating silica desiccant beads but any desiccants would do
