High capacity desiccant bin for Qidi Box - updated

Update 10/19/2025:  Some users have noticed that some brands of desiccant granules are small enough to fit through the slots of the original design.  I've revised the design with narrower slots.  I've tested the revisions with several brands of desiccant and feel I've found a good balance between good air flow and very little spillage of desiccant granules.

This model comprises a bin and “holster” to replace the small desiccant holders in the Qidi Box.  Two sets are needed.  

These units are installed using the original hardware and require no modification to the Qidi Box.

The bins have capacity for substantially more desiccant than the original bins.  In my experience, the slots are narrow enough to hold loose beads of silica gel without too many of them falling out.

I was able to print the bins in the upright orientation without issues.  I used ABS filament and the standard print settings for my printer:  .4mm nozzle/.2mm layer height/textured PEI printing plate.  I did not use supports.

I am able to remove and replace the bins without removing the filament spools.  I am also able to remove and replace the spools without disturbing the bins.
