Here are the drawings for anyone interested to build their own. I will put the links below too and I should thank @ColinKinner for sourcing the fans, adapters, etc!! We just copied him! #corsirosenthalbox
I have to say here that this didn’t arrive in time so my husband soldered the electrics to connect the fans to the adapter in the tweet above, but if you don’t have that stuff to hand wait for this connector to arrive!
