I printed it out and i found it quite hard to mount the base. I'd had to remove the X-axis wheel on the left, due to blockage when trying to slide in the base. The next thing, the stock hotend screws blocked on the fan guard of the base as well. I had to file a bit and pressed it down hard in order to slide in. For the pipe screw, i drill a bit with 1.5mm and it went in smoothly. Tested it with water beneath the nozzle and the fan 100%, kinda good...but i had to adjust the pipe a little bit to tune the angle of the air flow.
