Single Spool 4L Drybox

4L filament drybox

Background

The idea was to create a drybox with as few modifications to the food container as needed where the spool can be changed with ease.

Idea and Inspiration

This is a collection of things I've found to work well together and adopted them for a nice all-in-one set.

The base was inspired by mars gizmos design:

The spacer is a remix of this wedge:

Parts to print

What you need:

• Print the Filament Base first (without supports) - scale the model down to 10%
• Print 2 Roller

Print one Silica Lid and check if it snaps to the base
Depending on the filament you may need to resize it in small (0,5 - 1,5%) steps Optional but recommended:

Print the screws linked above
Depending on the filament I would recommend to scale the nut up a bit so the thread goes easy.

Print one Spacer for the temp-sensor/hydrometer
For bigger spools I'd recommend the original wedge above as it will push the sides better to fit bigger spools. ### Additional parts needed

Assembly

• Insert 2 Bearings into each roller
• Mount both roller to the base
• Fill the silica box in the base (approx 40g until full - way more than enough for 4L)
• Add the lid and set the whole base into the container
• Insert the hydrometer into the spacer-wedge

Install in front of the box where the grip is Optional:

Drill 10mm hole where you want to guide your filament outside

• Install the printed screw
• Screw in the compression fitting
• You might also hotglue a small (6x3) magnet from the inside of the lid to attach a filament swatch from the outside :)
