This adapter enables you to utilize notanumber's part cooling fan design on the Wanhao Duplicator I3 V2.1, utilizing a more efficient 30mm fan design. The stock part cooling fan duct is replaced by this setup on the front of the V2.1, offering ample space for normal PLA prints without excessive deformation concerns. In my experience, it has worked exceptionally well. I have added an optional version to allow centering the fan based on your specific setup requirements. I also increased the thickness by 1mm as I felt it might be a bit weak. The adapter's thickness is designed for my printer with the stock MK10 heater block and Micro Swiss all metal hot end set according to the manufacturer's instructions. However, since there can be variations in nozzle height between printers, you may need to adjust the height by using thin washers to raise the duct or even sanding off a little to lower it. I have my duct set less than 1mm from the tip of the hot end. I created this adapter and my duct from PLA, and last night, I conducted a 12-hour print at 245 degrees without utilizing the part cooling fan, worrying that the duct might deform and hit the print. Fortunately, it withstood the test unaffected.
