Double-walled expansion kit for the PrintDry Filament Dryer Pro. To dry and print with two more additional spools of 200 mm outside diameter, which means one dryer can serve more printers.

Package includes:

• Plastic tray x2
• Metal shafts x2
• Support bridge x1
• Big spool adapters x4
• Small spool adapters x4

For the single-walled Filament Dryer II, please use the single-walled Additional Chamber Kit instead. 

Stacking 

Due to the stackable chamber design, you can use multiple additional chamber kits per dryer; however, the temperature and stability decrease as you add more chambers. We don’t recommend using more than two additional chamber kits per dryer.
