I was thinking of investing in a small 3D printer to aid in my hobby, if I owned one my mediocre scratch building would most probably take a backseat lol.

Is yours a resin printer? I read somewhere that resin prints smoother with higher details than the filament printers but I don't know if it's true or not.

I've been looking at local sellers here in NZ but there are so many to choose from I don't know which to get.

That's a nice looking engine bell, it's the look I tried to achieve on my Saturn V build with the booster rockets.
