These are drains for a diy milling machine cabinet, they are for use in a 3/4" constructed enclosure... these are recessed into the ply with proper size hole saws... my specific mill enclosure for flood coolant is 36" wide, I ended up using 3 drains total.. one at each end and one centered.. ive also uploaded the files for drop in chip screens and a drain junction I designed if you want to use 3 drains like I did.... all barbed ends are for 1" i.d hose...

enjoy!
