Filament cleaner/cooler box

thingiverse

This project aims to create a filament cleaner and cooler box. It consists of three main parts - the FilamentBox, AirBox, and Clean/Dry box. The FilamentBox has a middle section with a sponge that removes dust and acts as an air barrier. The AirBox injects air into the filament tube to cool it down, and the bottom part is located under the middle section. All parts should be mounted in a way that allows free movement of the filament without touching the box. A tight fit between the top and air parts ensures no air leakage. The AirBox is ready once the 80mm fan funnel is in place, and an air chamber (middle part) stores and increases pressure through the connected top part. A hose or similar can connect the cleaner/cooler part to maintain pressure without excessive length. All three parts should be glued together after sanding for a proper fit. Don't forget to add a dust filter on the fan, and additional fans can be added for more pressure with the inner fan being the fastest. The Clean/Dry box removes fumes and moisture using a bottom part and two middle parts of different sizes. The assembled parts connect to the fan in the AirBox. A normal 80mm dust filter should be used to ensure no dust enters the fan, and "Silica Gel Cat Litter" is placed in the box to remove moisture from the air. Note that this design has not been tested yet, so dimensions may need adjustment. The project was made using Autodesk 123D Design, with additional help available on makerbotwiki.com.
