CoreDry | The All-Fit Desicant Core

"I was tired of switching desiccant holders,

every time I changed filament brands" — so at

D+, we designed one that fits all spool cores.
And yes… we might’ve gone a bit overboard.

At the heart of it all lies a two-piece capsule system.
It locks together with a satisfying twist, sealing the desiccant safely inside.
The capsule is perforated with a custom mesh pattern — a balance of 

aesthetics and function, allowing constant airflow while giving it a unique engineered look.

Surrounding the capsule is a two-part outer shell that fits neatly into any spool.
Its twist-lock design allows adjustable length to accommodate different spool depths.
Custom cavities along the shell ensure continuous air exchange, 

even when the spool is stored inside a vacuum-sealed bag.
Overengineered? Maybe. Smart design? Definitely.

When it’s time to refresh your desiccant, you don’t need to remove the shell.
Simply twist and pull out the inner capsule — fast, clean, and efficient.
