Max Air Desiccant Holder - Spool

This Max Air Flow desiccant holder has an easy twist lock cap and fill funnel. I found the twist lock cap much easier to close than the threaded screw type. This desiccant holder is intended to go into the spool center hole before enclosing in an airtight bag. It holds plenty of silica bead type desiccant to keep your filament dry for a long time. It has numerous vent holes including a center shaft with additional vent holes to quickly dry your filament and keep it dry. I designed it such that it requires no supports to print. 

If you print with ASA or ABS, you can dry the desiccant in a filament dryer at 65C leaving the desiccant in the holder.  If printed with PLA don't set your dryer higher than 50C, PETG at 60C.  Keep the holder away from the direct airflow of the filament dryer as the air is a higher temp coming out of the dryer and will deform the desiccant holder.

1/1/2014: I added a Fast Print version of the Max Air Flow Desiccant Holder. The second holder, DesiHldr_FastPrint.stl, prints much faster than the original and provides as much air flow. It took 40 minutes to print on my P1S.  It isn't as structural strong as the original but its strength is sufficient. I designed it such that it requires no supports to print in fact you may end up with a mess if you print with supports.  I would stick with the original model if your printer has problems with bridging. it printed with no problems on a Prusa Mk4, Creality CR6, and a Bambu PS1.  This model needs to be printed with the following settings:

    Layer height = 0.2 mm

    Outer and Inner Wall = 0.4 mm

    Seam Position = Nearest (recommended, not required)

    Wall Generator (Arachne)

    No Supports or Brim

    Wall Loops = 2 (Recommended, not required)

    In-Fill Density = 15% (Recommended, not required)
