Description

PDF

Here's a desiccant tray I use in the bottom of all of my 20qt Sterilite dryboxes.  I pour desiccant in them and they sit under all of my rolls of filament.  I like having it open so I can easily see the color of the desiccant to know if I need to dry them.  The shape is designed specifically so I can just transfer it straight over to my cheap Commercial Chef food dehydrator and throw it into one of the trays there.  With my tray extensions, I can dry a whole drybox at once … 4 rolls of filament and the tray of desiccant.

If you use a different nozzle size or a different infill pattern, you'll have to play around with the infill percentage.  It took several tests before I found that 42% was just small enough that the broken desiccant pieces wouldn't fall through, but left plenty of room for the air to go through.

Printing

The .3mf I've included has the settings exactly as I print it on my MK4.  They are:

  • 0.8mm nozzle with IS
  • 0.55mm DRAFT
  • Generic PETG profile
  • The pictures show California Filament's Cloudy White PETG.
  • 2 perimeters
  • Gyroid Infill @ 42%
  • 45 degree infill angle
    • This is only important if you print the one with the spout.  You want the second layer of infill to print toward the spout so the beads roll the correct direction.
  • 0.45mm first layer
    • This is so we get exactly 2 infill layers that are 90 degrees from each other.
  • 0 solid top layers
  • 0 solid bottom layers
  • Random seam position
    • When it was aligned or even nearest, the gaps I get at the seams can leave a vertical slit in the side.  You really want to use random here.
