This model is a set of accessories for the “Silica Dryer Spool Insert” by Brekel. While using this lovely spool insert with my filament dryer, i had some significant issues and made quite a mess. Initially, I had a lot of trouble filling the basket without my beads missing the narrow target and flying away into the abyss. Then, once sealed in, I had issues with full sized beads being able to escape between the basket and the spool as the walls of both flexed, and with small or broken beads escaping through the slats. To combat these issues, I created some accessories for the original model.

The accessories include:

• An endcap
  • This goes on the open end of the basket and ensures that no desiccant beads can sneak out between the basket and the spool wall.
  • Print this with the flange flat on the build plate to eliminate supports.
• A funnel ring
  • This expands the outer diameter of the basket during filling, making it easier to fill without making a mess.
  • Print this with the large diameter end down, to eliminate supports, and with a brim to help the small contact area stay stuck to the build plate
• A center cap (inner funnel)
  • This seals the center of the basket off while filling, and prevents desiccant escaping down into the center of the spool.
  • Print this with the flat end on the build plate to eliminate supports.
• A Filter scoop
  • This will help to filter out all the pieces of the desiccant which are too small for this basket and will fall out into your filament dryer or onto the floor.
  • Print this with the flat side on the build plate to eliminate supports
  • This part is comprised of a main body and a modify body. The modify body is placed over the floor of the scoop and is set to have zero top or bottom layers. Then the sparse infill type can be set to “Honeycomb” and the infill percentage can be modified to get the desired hole size. With a 0.4 mm nozzle, I found ~20% to be about right for the size holes in the basket, but your mileage may vary. I placed a primitive cylinder of the desired size on the build plate compared it to the infill holes in the slice preview to help get it dialed in.
