120mm to 92mm PC case fan adapter

I wanted to use a 92mm fan in a computer build but there were no screw holes for it so I made this.

Print at 0.2-0.28 layer height, recommended to use 3 walls, 3 top/bottom layers, and 15-30% infill but you can probably get away with less. I used PETG. Im sure PLA would work but I was worried about it getting soft in a toasty computer case.

The screw holes are small and are designed to allow the fan screw to cut its own thread. Fan should be screwed in on the flat side as shown in image 2. 

2 versions available, one has less surface area and decreases print time/material usage bya a substantial amount :)
