I made this to improve refrigeration system of my 6 GPUs Mining Rig, I hope you like it.
You must print all of these pieces:
6x Pilar hexagono.
6x Soporte superior grafica.
6x Soporte inferior grafica.
12x Larguero grafica.
I made them at 0.3 layer high, except Pilar hexagono, this I made at 0.2 layer high.
With a bunch of M3x16 and M3x20, some zip ties for fans and wires will be ok.
