CNC mist dust shoe

thingiverse

This is a CNC dust shoe that supports compressed air cooling and mist lubrication. - Achieves superb dust extraction for flat work pieces thanks to being independent from Z - Directs pressurized air into the vacuum intake - Keeps router air flow away - Doesn't limit router Z travel Designed to accept 35mm vacuum adapter. Requires 8mm (1/4 thread) and 4mm (M5 thread) connectors for air and coolant pipes respectively. Additionally requires 2x10mm rods with threads only on their ends. Using M10 threaded rods throughout is NOT advised as they get stuck in the clamps. If you don't have a lathe to make them, try 3D printing or drilling our the threads in the glider and gluing the non-threaded 10mm rods in place. I only use mist cooling when CNCing aluminum (without it the end mill clogs up in 5 seconds), no need for mist/air when cutting wood and plastic.
