NOVA3D Elfin ventilation

I designed this for my NOVA3D Elfin. This is only a test design(i have printed the base adapters, and i am still thinking to improve the fan adapter in order to be used with a much simpler fan)
If someone has another idea, i can modify it. I can also modify the base to be only one part(i have an Ender 3 and this is the only solution i found)
For this version you will need:
- 4 screws M3x10 (or longer-i used M3x16 DIN912 and it works)
- 4 nuts ISO4032
- this is optional: 4 washers DIN125-1A
- 1 inline fan with 100mm diameter. I will try to make another version with one normal fan maybe 60/80mm DIA
