This one was a special request from a site visitor, but was so impressive I had to give it a shot...  Printed from PLA my best guess is it will be roughly 18" x 18".  Much like other landing pads, however it is scaled at 130% and meant to have 4 combined into one.  PLEASE NOTE PRICE IS FOR ONE PIECE ONLY!!!!  As I am not planning to stock this, inventory will be printed once ordered so may take a bit longer to ship since this is a long print
