Spool holders and desiccant container for the Kobalt X-Large tote (https://www.lowes.com/pd/Kobalt-Kobalt-24-Gallon-Weatherproof-Tote/5001968209)

Holds at least 16 1KG spools.
The container holds ~1/2 liter of desiccant.
Requires 250mm build area.
I tested with both PLA and PETG; both seem to hold up fine. 

Recommended:
3+ perimeters
20%+ infill (any infill pattern that's good for load bearing - I used triangles)
Bluetooth hygrometer (since this tote is opaque)

There are 3 versions:
PVC - Use 1/2" schedule 40 PVC pipe. It will hold a 550mm long pipe; cut to ~545mm to ensure it fits.
PVC Sleeve - Same as PVC, but with printed sleeves. This looks nicer but is a bit of a pain to glue in place. :) 
Fully Printed - Uses a printed pipe instead of PVC.

1. Print two of each spool holder sections, two brackets, and the desiccant container & lid.
2. If using the sleeved version, put the PVC pipe through the sleeves.
3. Put the ends of the PVC or printed tubes in the end sections of the spool holder.
4. Put 2-3 drops of superglue into the holes near the base of each section, then join them together.
5. If using the sleeved version, lay a thin line of superglue over the PVC where the sleeves meet, then stick them together.
6. Place the spool holders in the tote, then place the desiccant container in the middle.
7. Join the two spool holders together using the brackets. You can superglue them in place if you want.
