This was much closer than others I printed & tried. However, I had to sand the outer edges (the longer sides) & squeeze it with some channel locks to slightly bend it inward to get it to fit my fan. I may have printed it with the wrong settings making it a little too big. But after a little elbow grease, it fit & I know it's not going to fall out like the one that came with the ANET A8. Great job & Thanks Murkser!!
