Fitz,
I picked up an Elegoo Neptune 4 Pro a couple of days ago, along with a roll of white and a roll of gray PLA filament that should arrive today. There was a length of white in with the printer and it printed the mini buddha file that came with the package just fine, so I decided to try the rest of the filament out on a 1/144 Halberstadt DII (I think).
Didn't come out so fine, underneath the wings was real "stringy" (?) but the undercarriage and fuselage were good. I'm hoping it is nothing more than using a "free" file I found on the internet, which didn't have any supports under the wings or anywhere else. I purchased some files from Wargame3D this morning, hopefully they'll be more "refined" and they include supports.
