Giant Impact Hypothesis key stages with stand

Stages are numbered 0-4.
2 and 4 need tree supports due to some overhangs.
I would recommend printing the 5 poles at different heights. For example, the first pole I made was 5cm long, then I increased each subsequent pole by 2cm.
I would also recommend using a brim for the poles (also 2 and 4, because of supports) and printing them lying flat.
All were printed in an Adventurer 3 (FlashForge).
