K40 Air and Smoke Assist

02/19/2019 Added 3/16th version per request, maybe it will work. 07/28/2018: Increased the fan duct thickness, it was printing thin. 07/27/2018: I changed up the bracket for the laser head after I pulled the threads out of mine. I added slots for M3 nuts. I also added hose connector for top of copper tube. I remixed a few parts so that I would have smoke assist while engraving, but I also wanted air assist and smoke assist while cutting. This works pretty well on my K40. The duct is sized for a 40x40mm fan. Assembled with four 3mm bolts and nuts and roughly about 3 to 4 inches of 1/4 inch copper tube, just cut it to size. The parts I remixed: Air assist by mbridak.: https://www.thingiverse.com/thing:869652 K40 Fan from sebecam2000, which was a remix of K40 Fan from d4d13. https://www.thingiverse.com/thing:2724230 universal tube creator with holder from Winne. https://www.thingiverse.com/thing:623915
