I've made a kit card model of the helicopter I really like. This model can be displayed everywhere and can be great gift.
Printing instructions:
Layer height: ≤0.15 mm
Infill: 100%
Material: PLA (PETG might work too, but I have not tried it)
Supports: none
Assembly:
To separate pieces use scissors or tweezers. Assembly is quite easy, just follow image below. Model should work without glue, but depending on your printer a drop of super glue might be helpful :)
The author marked this model as their own original creation.
