This is a revision of Brandon Raineri's Spool container. One small frustration is that it's so well designed that it was hard to tell which end opened as the “Cap” and which was the container or “cup.” This led to a good chance I was spilling silica beads all over 😅.

The major revision here is adding a label to the cap part with a small text addition to label it CAP.

I've adjusted the speeds in my print profile and finish strategies which I like a little better.

They fit Bambu Lab spools perfectly. Also Hatchbox PLA spools (image included).

The filament must be dry for quality PETG printing - holes won't be clear and you'll get buildup. Also, vent your machine.

To Assemble

• Push the end caps into their appropriate (size is key) parts.
  • Use superglue or E6000 linked below if you'd like to assemble caps with bodies (not the screw mating though).
• Add desiccant to the container.
• Screw together container on the spool.

Tip: Dessicant is reusable. Put beads in a glass container and microwave for 1-2 mins until color returns to normal. Let cool and reuse.

The 70c spool does not work with this version

Trouble?

• If you're having any issues printing, make sure to dry your PETG to <20% humidity.
• Lower the volumetric flow rate to 9 mm/s in the filament profile.
• Slow the print speeds.
• Easiest cure-all fix is to just put the printer on Silent mode which prints at 50% and that usually solves a ton of PETG quality issues.
• Use nano adhesive on bed if you're having sticking problems.
