The goal of this design is to allow a lubrication and chip clearing module addition to a CNC router. This system consists of an external unit which served to feed the air and lubrication with an actuating arm mounted on the spindle to better direct the fluid/air onto the tool piece. This simple and easy solution would allow individuals to use their CNC Router with metal.
Soldering Iron to use filament welding method to connect parts
Use solding iron to melt filament together. A short piece can be ran through holes and melted on either end. Another option is to melt along the edges where two parts meet.

Arm Sub-Assembly
Use filament welding method to connect "Socket Flange" to "CNC Mount"
CNC Mount and Socket Flange
Use filament welding method to attach both "End Hose Clip" pieces to the other "Socket Flange"
End Clip Top
End Clip Bottom
Use the "Socket Ball Long Adjusted" (2), "Ball 40mm Ball Vert" (1), and "Locking Nut" (4) to assemble complete arm.
Fully Assembled Arm
Peristaltic Pump Sub-Assembly
Feed Lubrication Tube through Pump so the desired length is hanging out into lubrication bottle
Mount to lubrication bottle
Trim tubing to appropriate length (length in this case is from the router head to the box location)
Peristaltic Pump Front
Peristaltic Pump Back
Fan Sub-Assembly
Cut and Strip neutral wire of air mattress pump to place relay in the middle
Wire relay circuit to Arduino Uno (wiring) and connect the stripped ends of the power cable to the NO contacts.
Compile and upload the Arduino sketch to the Ardino Uno and connect the board to a 5V power supply
Full Electronics
Final Assembly
Place Peristaltic Pump Sub-Assembly in Box
Secure to box with glue/tape/zip ties
Place Fan Sub-Assembly in Box
Secure to box with glue/tape/zip ties
Run tubing from two assemblies to the "CNC Mount". Feed through the holes and place in "End Hose Clip" Adjust arm to angle tubing in the desired direction and tighten "Locking Nut"s.
