@MirageC , I was trying to work with the files out on Github for the HevACS that are marked for Oleg. When I open them in simplify 3D they don't slice correctly as portions show as missing after slicing as if the part is not solid. Are there more updated files than what is in Github? If not I'll try to similarly recreate what is here. I was able to use the 515mm dual fan base and the fan holders, but the other parts won't work. Thanks.
