Creality CFS is a great solution to keep your filament in a ready-to-print condition due to seals and desiccant. If you put in your filaments immediately after its opening, even dryer is not necessary for PLA/PETG/ABS/ASA.

But, desiccant boxes have inconvenient covers, are using not so big bags, and lay under the spools. So i need (with integrated Space Pi dryer) removing spools and change the desiccant every week.

This mod is adding big amount of a cheap bulk dessicant, in a box attached with magnets, easy to change it without removing the spools. As you can see on pictures, humidity is 12% after few weeks, with 40-45% in the room.

Printed with Creality Hyper PLA. For this model are necessary to have a calibrated flow and pressure advance. With standard profile (without extra calibration) i have better results with white Hyper PLA.

Needs 16pcs of 6x2mm magnets and 3pcs M3x8mm screws.

Assembly order:

1) Press-in the magnets into the base with an equal orientation.

2) Attach the second row on the installed magnets and press it into the box, one after another.

3) Press-in the (cover holding) magnets into the box with an equal orientation.

4) Attach the second row on the box cover magnets and press it into the cover, one to another.

5) Using the base as a template, mark up and drill with 2.5mm bit three holes in CFS (place see on pictures). Attach the base by M3 screws.

6) Fill the box with a desiccant and shake it well for a broken particles fell out. Put the cover on and attach the box into CFS.

This box is designed for granules of at least 2mm in size (this is usual desiccant size). I'm using a сat litter with indicators (blue).
