MP Select Mini E3D v6 Triple 30mm Cooling Fan

thingiverse

I didn't have one of the big 50 mm radial fans, but I had a spare 30mm fan on my workbench, so I came up with this solution. I think it works really well. The main difference with this design is that the angle of the fan is more in line with the shroud for improved airflow. The shroud also points very accurately at the part below the nozzle. Use PETG for the bracket parts and main fan, but you can use PLA for the side fan if you prefer. To get my Benchy to print as shown in the photos, I had to fix the z-wobble with a printed clamp, calibrate the extruder to get the right flow rate, manually tune the PIDs, and cool the control board. It was all a hassle, but it prints nicely, albeit slowly. My PIDs are set at P30, I0.06 D150. **Printing on a Select Mini: PETG is tricky to start with on this printer, but I used very slow speeds (10 walls, 20 infill). I employed coasting, but not wiping. Wiping left really ugly layers and delamination. I would try to print everything with the stock hot end before switching over to the E3D v6 hot end. It has its own learning curve.** The Fan Shroud Clamp and Zero Offset Bracket are originals from USWaterRockets. See the remix info for more details.
