I made this design to be 3D printed in 1/4 scale for a project and it worked really well.
There are some thin walls (heatsink) that may come out just good, but other than that the model if printed down to 1/4 scale looks great.
This comes in 4 parts, 2x Fans, the main body and a plate.
Print the fans flat to the printing platform with no supports, the main body vertical with the connections side facin the platform and the plate at 45 degrees angle with supports as required
I have only printed it in resin, so I don't know if woudl work for FDM though.
Any questions just give me a shout.
Thanks!
