This is a great model for test prints! I've made 3 so far on my 2 day old printer. Every scale I have used reveals more detail
The first was at 75%, second at 100% and third at 150% scale. I plan to do more - a vase mode version will be my next experiment, and then at some point - probably when I get grey pla, a 1/144 scale. (approx 30cm wide)
The two smallest use .2mm standard print settings, while the larger one came out fine testing a .4mm draft mode.
Unfortunately the engine is no good at these scales - at 75% it doesn't print at all, at 100% it barely prints and is unusable. At 150% it may be usable, but wont look perfect. I think the engine will work from 200% upwards - the engine fins need multiple layers - check your slicer.
Next - the Asp - my current in game ship.
Scale 200% + before you try the engine. Print on end with no supports.
