Ultralight 4g Copter

Seeking a nostalgic trinket, I found existing dragonfly toy designs underwhelming—they simply didn't fly high enough.

So, I crafted my own, and the results are quite satisfactory.

Employing a slender blade design and a hollow shaft, the overall weight is remarkably light; a model with an 18cm wingspan uses approximately 4.2g of PETG filament.

To ensure structural integrity, I opted for a lay-flat print orientation, aligning all components along the x and y axes. This enhances strength, preventing breakage from minor impacts. However, this method results in a less polished support surface. Optimizations could be achieved via adjusted support settings or the use of alternative support materials. However, for a casual project, such refinements are unnecessary (Don't tell anyone, but I'm not exactly eager to waste more filament!).
