Under garage door vent

I Designed this to fit under my garage door so i can exhaust fumes from my K40 laser engraver.i used a 1x4 wood to match the height so the garage door can sit flush to prevent air gaps under the doori recommend you print this with PETG. you just need to glue it together.a standard 4 inch or 100mm exhaust hose will fit onto the hose connection.I HIGHLY RECOMMEND YOU ADJUST YOUR GARAGE DOOR HEIGHT SETTING.
