Sunlu Filament Dryer SP2

The SUNLU FilaDryer SP2 is a 2-in-1 filament dryer and storage box in one compact, stackable unit. The heating base and storage box separate into two independent pieces - dry your filament while printing, then detach the box to keep spools sealed and humidity-free on the shelf. Multiple boxes stack freely (up to 3 recommended) to maximize your workspace.
