We have a dehumidifier in our laundry room. We run the hose over to the floor drain, but it requires you to leave it up resting on the hose. So I dimensioned the floor drain, and made on one of the holes big enough for the hose. I then put piping from that hole to the center of the drain. I used PETG to print. Before printing the whole thing, I would make a print of the top piece, maybe 2 layers thick to make sure of the correct fitting in the hole.
