DIY Filament Dehydrator

This is based on the multitude of DIY videos and articles about adapting a food dehydrator for 3D filament use.

This extension collar is designed for the Rosewill Countertop Dehydrator which looks mysteriously like the PrintDry Drying System's dehydrator.

The DIY directions show cutting the grids out of the stacking rings to make room for the filament spools. When I bought the dehydrator that was my plan, but after using it to recharge used desiccant packets, I decided to keep the grids intact. After some measuring, some test prints and gluing I came up with this design.

With this design, two reels can fit in the dehydrator, and the grids can be used simultaneously to recharge desiccant packets. By printing additional collars more than two reels could be accommodated.

The Cura settings that produced the best results:

Printed with a .4mm nozzle

Line Width: .39 mm

Wall Thickness: 1.2 mm

Print 5 panels to complete the extension collar.

Post-Printing

Glue the panels together to form the ring. I used Bondini BX3 Cyanoacrylate glue.

To use the extension collar:

• Place one grid ring on the dehydrator base unit.
• Place the extension collar on that ring.
• Optionally put additional grid rings on top of the extension collar
• Put on lid.

On the Matterhacker's web site is a table that shows the suggested temperatures and drying times for different materials.

There may be a limit to how many collars and grid rings can be used before dehydrating becomes inefficient. I believe that increasing the volume and load on the dehydrator would increase the processing time. I haven't been using it long enough to find out.
