Airbrush Sprray booth and ventilation system

This is an overengineered spray booth primarily intended for air brushing. The 3d models covers all the part needed for this build this booth with the exception of wooden frame, the polycarbonate panels and electronics. 
 

The main feature of the booth is a funnel with channels that direct the air flow upwards and concentrates it into a duct.

• The funnel is split into 5 distinct parts so it can be printed on a normal MK4 type printer. 
• Mounted to the front of the funnel is a filter holder. The filter holder is designed to hold 2 typical airbrush booth filters of up to 3 cm. 
• The filter cover for the filter holder is held on with 8x2 mm magnets 
• The dimensions of the duct is optimized for this fan:

• There is a ducting part with a honeycomb bottom intended to hold a carbon filter. 
• There is a stator to help increase throughput through the carbon filter. 
• There is a honeycomb “carbon tray” for holding active carbon pellets. To use, print 2 layers, pause, add a fine fabric like tulle over the print, continue. 
  • I created a “lid” for the trays using the same technique but splitting it in the slicer to get a thinner print. 
• Finally there is a crown to top off the model. (just for decoration) 

In addition to the funnel are various rails and connectors used to build the Polycarbonate top and sliding sides. I used 3 mm polycarbonate and 7 mm plywood. 

The rails have 10x3mm channels in this to house the LED strips. I recommend using a cob type of strip to give a smoother light distribution and rated for outdoors. Since this is for painting would also recommend a high CRI value (at least 80+). Higher value means better color representation. 

Note: It is common to do these DIY booths with computer fans. They “work” but I needed something with more umpf to push the air through the active carbon granulates. I welcome is any one want to do a remix with a stack of computer fans. (I will try this myself when I find the time.)
