I wanted to first say thank you for taking the time to download the file here on Thingiverse for all to use. I myself was being lazy and wanted to find something quick to use to make a printable fan of this size. In the process of using this design and back engineering my own fan with a set of micrometers I found that your measurements are off + or - 3mm and is not a true representation of the actual size of a 40x20 fan. I don't mean any ill will or callousness, I simply don't want anyone to use this design for a project only to discover the measurements aren't specifically correct. The design definitely helped me with creating my fan so thanks again.

Hi Rygar1432
Thank you for the note. I made this model based on one of the fan I had. I used digital caliper for measure dimensions. Measuring errors shouldn't be bigger than -+0,2mm. I based on the fan like this:
