Elegoo has three slightly different sized build plates on the original Elegoo Saturn and it is not clear which version you have without measuring the build plate. The original Saturn build plate was 192 x 120 mm and the new plates are 196 x 126 mm and 192 x 126 mm. Since the build volume listed is the same on all versions, we recommend not ordering the Saturn kits until your printer arrives and you are able to take physical measurements.
