Printed the whole thing in one piece, upright, 45 degrees rotated, to get it as large as possible on my 200x200mm UM2 printbed. I recon printing it on it's side in 2 halves would give a lot more overhang than just printing it upright.
0.8mm nozzle, 0.25mm layerheight, 50mm/s. Took 6 hours to print. In the middle of the printing, at the easy parts, i have had the printspeed set to 200% to reduce printtime.
The water leaks veeeeery slowly through the plastic. Like 1 drop after 1 minute. Just got to put a layer of varnish on the inside to fix that. Or water the plants quick enough.
