Description
PDFThis is the easiest way to extract fumes from your room or 3d printer by simply plugging it into a USB port - no klipper configuration or custom gcode needed.
Can be printed twice and placed on each side of a 120mm fan to create a cheap inline fan using 4inch ducting, or used as a wall extractor.
LINKS TO THINGS YOU MIGHT NEED| 84-108mm Clamps | To secure the ducts. Alternatively you can use duct tape |
| 4in Flexible Ducting | The main ducting used to vent the printers outside |
| M3 Self Tapping Screws | 2 Screws to secure the collector to the wall |
| 1/4 in hex shank extension | You might need extra length for your driver bit to reach |
| Duct tape | For extending ducting or as an alternative to clamps |
| Printable 4in duct bracket | I designed these to easily mount the ducting to a wall |
| Printable 2:1 collector | I designed this to merge 2 ducts into 1 |
| 120mm fan (5v) | Can plug into the usb port of a 3d printer for easy extraction |
| Fan extension cable | So you can move the fan further away from the USB port |
