Claymore On-Spool Desiccant Holder

What I have learned over the years: New filament is never dry!  Hence this design to help keep it dry.  

How I get my filament dry?

1. Unpack your new filament
2. Dry it using a dehydrator, because that is what they are designed to do.  Here is my setup if anyone is interested.
3. Pack them up in a vacuum bag with this Claymore to ensure they stay dry.
4. Bonus: Add a humidity sensor (here) to indicate issues with moisture before you need the filament.

Design Features:

1. Capacity to hold approximately 50g of desiccant, which is more than enough (see DIN 55473 for more information about desiccant and TMEs).
2. A wide clip to attach to the spool and is wide enough for cardboard spools.  
3. Micro-Threading intentionally introduced to help keep broken pieces of filament inside the container
4. The clip has a built-in print support which can be easily snapped off using pliers.  No need to add printing supports!
5. Additional filling funnel to aid with filling the container.

Experiences:

Consumer grade desiccant (what you and I can buy online) is usually B-Grade and contains a lot of broken pieces.  Most desiccant holders have holes which are too big and most of these broken pieces start falling out over time, making a mess.  

I you don't have a dehydrator, then simply place two of these into your vacuum bags and let the sit for a couple weeks.  Most of the moisture will be drawn out to create an acceptable print.

Happy Printing!
