I promised to post paintbooth I'm building long time ago. Well finally I built it, so here's the pics. Down draft design based on these 2 articles:

Pictures shows it with the associated mess.
Front View
Back View
Material used: 1pcs plywood 4X8', & some support wood strips
Dimension: 32" wide 24" deep, total height 29" ( a bit big but I use rattle-cans remember

)
Fan: a brushless table top fan with motor polarity reversed, on high I can use the booth as a carving booth as well, clear part u see from back is an acrylic drawer to collect the shavings & dust plus is the where I stuff the filter while painting.
PS: Don't ask me questions till u've read the 2 articles

:-D The design & requirement should be apparent from what's explained in the articles.
