40mm to 50mm exhaust fan adapter

I designed this fan adapter to replace the 50mm fans in my Tevo Tornado with 40mm fans. You need to print two of these to secure the fan with 2 screws.
3.5m screws will create their own threading, if you use smaller screws you may need to use a nut.
It's important to note that this adapter is only suitable for exhaust fans and noctua fans (both intake and exhaust), for intake fans, see my other design: https://www.thingiverse.com/thing:2667177
