If you own an X Carve CNC or any other CNC that uses the Dewalt 611 router for its spindle, this simple 3D printed attachment will save you a ton of cleanup and suffering when cutting carbon fiber submerged in water. Since carbon fiber dust is extremely toxic, it is necessary to cut it underwater for dust control and proper cooling. However, the Dewalt 611 spindle inconveniently blows air downward when running resulting in water getting thrown all over the room. This simple 3D printed attachment screws onto the bottom of the Dewalt 611 and redirects the downward airflow off to the sides to prevent it from disturbing the water around your bit. Also, even bits without an up cut can fling water upward and into the router which this attachment prevents by creating a small "skirt" around the base of the router controlling the splatter.

Note: For those of you asking "what kinda submerged cut tray is that?" we designed and printed a custom tray that used 3D printed hold downs for cutting carbon fiber underwater. After extensive testing though, it became clear that the hold downs just weren't reliable enough so our new method involves creating a sandwich between a flat cookie tray, a piece of 1/8" acrylic (as a waste board) and your carbon fiber piece. Everything is just stuck together with 3M VHB adhesive tape and it works every time! See the attached photo for more details.
Polymaker PLA or PETG
Black is best as it won't show the carbon fiber dust as much
Print with at least 3 shells for maximum strength.
