12/14cm 猫头鹰风扇罩优化版 Noctua High-efficiency fan grill

 12.6更新:增加大开口的版本，原版圆口的对于某些扇子进气遮挡有点多，非猫扇真想用建议大开口版本

原模型文字太丑，优化了一版，并增加14cm版本

去除文字，进风侧电机处增加倒角，方便辨识方向。原版圆内径只有112mm，修改为116mm，14cm版本为136mm。厚度增加至2.6mm，强度更适合打印件。四角r角修改为r8，原版r8.5有点奇怪，不太适合其他风扇，并增加倒角

建议有倒角那面作为底面，不然太难看了

Remove the text and increase the chamfer of the intake side motor to facilitate the recognition direction

The original round inner diameter is only 112mm, modified to 116mm, and the 14cm version is 136mm

Thickness increased to 2.6mm, and the strength is more suitable for printing

Corner is modified to R8. The original R8.5 is a bit strange, it is not suitable for other fans, and it increases the chamfer
