thingiverse

This is a 3D model of a Delta Electronics EFB0412HHD fan. It is not intended for printing, though it should be printable. The purpose of the model is to help with the design of fanduct-type things. I'm getting ready to design the next step up from my Z-19 project. Check my designs, if you don't know what I'm talking about. I'm not happy with the level of hot end cooling provided by the fan that comes stock with the Creality CR-10S. So, besides upgrading the model cooling blower to a 5015 type, I want to also upgrade the main fan. The original fan is 40x40x10 mm. This one I've selected is 40x40x20, and the increase in size is handsomely rewarded with stellar specs: * Air stall pressure is 9 mm H2O, well above the average for its size. * Air flow of 0.27 m3/min (9.6 CFM), also above average air flow. * Acoustical noise is 30.5 dB, which is whisper-quiet. I'm in love with it, and I've just ordered it, hasn't been delivered yet.
