Cereal dry box

This is a remix of Redbluefire's excellent spool and desiccant holder for cereal dry boxes.  

Update 3/17/25 - I've posted a simple PTFE tube connector for connecting the PTFE tube of the dry box to the PTFE tube in the printer.

I split the spool and hygrometer holder parts from the desiccant box.  I wanted to be able to take the desiccant box and put it in my filament dryer, without having to empty it, when the desiccant needs to be renewed.  I printed the desiccant box in PETG, and the rest of the parts in PLA. 

I use a Sunlu S2 filament dryer, and dry the desiccant for 6 hours at 70 C.  To prevent the desiccant box from coming in contact with the filament dryer heater element I designed a small platform for the desiccant box to sit on.

This also includes a cereal dry box cap that is a remix of cap in Prism_Sync's Economic Quick Swap Filament Dry Box.  

I also included a cap for the 4mm PTFE to seal up the box when not in use.

All the 3D printed parts needed for the complete dry box are included here for download in the .3MF file.

In addition to the 3D printed pieces, I used the following parts
