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.

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

• Cereal boxes : https://www.amazon.com/dp/B0CFLJCJSF?ref=ppx_yo2ov_dt_b_fed_asin_title 
• PC4-M10 connectors : https://www.amazon.com/dp/B086W9HZDK?ref=ppx_yo2ov_dt_b_fed_asin_title
• Mini hygrometers : https://www.amazon.com/dp/B0CXHS6CYS?ref=ppx_yo2ov_dt_b_fed_asin_title
• 4mm PTFE : https://www.amazon.com/dp/B0D4RBVD3D?ref=ppx_yo2ov_dt_b_fed_asin_title

For the spool and desiccant holder, I split the desiccant holder from the spool.  For the drybox cap, I added new M10-1mm threads.
