Venturi Fan Intake for 3" vent Laser Tents
thingiverse
This is an adapter for Laser Tents such as Creality that have 3" vent ports out and come with wimpy fans that do not adequately evacuate toxic fumes from the tent. This set dispenses with the cheesy fan and allows the connection of a 4" duct and the addition of an Inline Fan of considerable power. The Venturi inside works GREAT at sucking out all of the smoke and fumes if connected to a 4" system with an Inline Fan. In one photo you can see the fan I use, it's 10 speed PWM controlled and POWERFUL. This is an easy mod that makes the Laser Tent truly smoke free!
