Kobra S1 Poop Chute + Exhaust Adapter v2

For the hose adapter, use the male part from the following system: https://www.makeronline.com/en/model/Magnetic%20100mm%20Exhaust%20Hose%20Adapter%20System/256548.html?trackModuleType=10

What’s New in v2?

• Uses 5 mm diameter magnets for quick and easy installation and removal when the extractor is not needed.
• Optional supports: the supports are now completely optional and very easy to remove.
• Includes a small disk that can be used to support the exhaust outlet if the magnets being used are not strong enough.

Other Features

• Removable Basket
• Works with external spool mounts without interfering with the filament path.
• The chute is designed so that it never blocks the stock Kobra S1 exhaust vent. Airflow remains unobstructed, allowing fumes to exit as intended.
• Built-in port compatible with standard 100 mm ducting. You can attach ducting directly to this adapter to channel fumes outside or into a filtration system.

Why?

Printing ABS, PETG, nylon, or any filament with odor or potentially harmful emissions? This design gives you a cleaner setup by actively extracting fumes. The ducting allows you to route exhaust air out a window or into an air purifier, reducing fumes in your room.

Personally, I also use the extractor for PLA.

Tips

• Use semi-rigid 100 mm ducting and make sure it’s well sealed to avoid leaks.
• Position the adapter and ducting so the hose runs smoothly without kinks.
• Print the chute in a material that tolerates the temperatures of the filament you plan to use.
• I tested it in PLA printing PLA and it works fine, but your mileage may vary depending on your environment.
• Periodically clean the basket and check for buildup inside the ducting.

This is an updated version of the Kobra S1 poop chute with integrated exhaust extraction, designed to keep your printer safe and your workspace clean when printing plastics that emit fumes.
