Turns out the big shell I made to keep the dog hair / etc out didn't work nearly as well as I'd intended, so I removed it for easier access to the printer, and to take up 2/3 less space on the table. Then I moved it to a "new" table:
I got a shipping crate that was being tossed out that was made from decent plywood, though poorly assembled using staples and nails that didn't really hold it together. I reassembled it slightly differently than it came (the large plywood piece was the bottom, just above the "pallet jack" boards), to turn it into a table to use just for the 3D printing stuff (to free up my worktable for it's original purposes). I used drywall screws (salvaged mostly from other tossed-out fixtures, etc) to reinforce the insufficent nails/staples and make it a nice solid structure, moving the long crossboard from the "front" to the "back" to better triangulate it, and the front and top center crossboards to the ends to better triangulate those.
So now the broken printer is on the left end of the table, the stack of filament is in the middle, and the working printer is on the right end. I haven't gotten to putting the filament into the gamma vault with saved dehydrator packets to keep it dry, and putting the GV under the table; or mounting the power strip(s) to the table, and a light strip over it, and adding a little toolbox to store all the things used with the printer, spare parts, etc.
I also have a heat lamp I may add to the table on a gooseneck to keep the printing area warmer to help certain prints.
I have some clear plastic I may make a less bulky enclosure for the printer to help with that (even if it doesn't keep dog hair out).
JellyBean's waterbowl is still to the right end of the table (at the end of a long carpet to catch her drips as she walks away from it), and I"ll probably need to add a shield to the end of the table so when she lifts her head out of the water and shakes it, it doesn't splatter all over the printer(s). Can't really move the bowl, as it has to be at the end of that carpet so she doesn't leave a slime trail....
