Are you fearful that your favorite filament fills freakishly fast with fluid, causing fatal flaws, and find yourself flinging fountains of fecal failures right in the trash? Fret not, faithful followers, because the answer is, 

The PolyBox Pro

If you hail from the humid south like me, you're also finding that keeping  your filament dry and prints looking decent is a constant battle. I went with Polymaker but I've never been a fan of the baby blue plastic desiccant box. I use orange, color changing silica, and against the blue, it always looks saturated. And 90% of the box is solid plastic with only a few holes for airflow. So I created the PolyBox Pro to fix these issues, and for good measure printed mine in Overture's Transparent PETG so the desiccant color is obvious from across the room. Every side (but the feet and hygrometer frame) is hole punched and ready to accept moisture. 

Specs:

Holes: 1mm (diameter)

Hole Spacing: 1mm

Row Spacing: 2mm

• Model is in PETG but PLA works as well (remember to change print settings)
• If printing in transparent, set infill to 100%, rectilinear (or aligned rectilinear), and angle to 0%

Printer Settings:

• 0.15 layer height
• 100% infill
• infill pattern - rectilinear
• supports (paint on) only on the feet and hygrometer floating frame section
• no fans

And if you're looking for a 2nd box for the rear of the Polymaker, check out Welding Jar's “Polydryer More Desiccant Containers (MDC) Mod” [https://makerworld.com/en/models/1465390-polydryer-more-desiccant-containers-mdc-mod#profileId-1528618](https://makerworld.com/en/models/1465390-polydryer-more-desiccant-containers-mdc-mod#profileId-1528618)

His looks similar enough to match, and there are multiple additional boxes to use in your Polymaker. 

I hope you enjoy!
