Has finished set up my Gunpla workstation ^^
Basically is ok, just that might need adding another exhaust fan on window as wife said still has some paint smell even she is in master room (my workstation is actually in guest room & I didnt close the door while painting).
Use self made piping (made by 1.5ltr water bottle) lead the air out. This is actually learn from my brother, Kok Fon ^^
