Desiccant Container – Prusa Spool (No Flange)

Description

Desiccant container to suit filament spool core.  Intended for desiccant beads >3mm Diameter. I use the “Blue Indicating Silica Gel” from here.

This later had a flange added to make repacking of the spool on the bag easier, and I also have a special funnel to make filling easier.

I wanted to create a container to hold desiccant for my Prusament (filament) when in storage in the as shipped bag and box.
There is not much room left, so I decided to use the hole in the spool.

This container is designed to be an easy fit in the spool core hole. There are slots all around to provide air contact. I also designed in a core tube into the container to allow more air contact on to the desiccant, this also serves to hold the thread to secure the lid.
