Glowforge 4" to 2" tube attachment

thingiverse

This is a custom tube attachment designed for the Glowforge exhaust hole, not an official product but it makes it possible to attach a 2" tube to the standard 4" exhaust opening. We couldn't locate any available tubes that fit securely into the exhaust hole, nor were we able to find any suitable adapters that convert 4" to 2". To make one myself was the next logical step. To ensure smooth airflow, you will need to purchase rubber tape or use duck tape as an alternative solution.
