No Glue required; the idea of this was to make it almost like a Mr. Potato head with easy parts to insert while making sure they don't fall out on their own. Pieces can disassemble but are a bit tight fitting.

Though a couple pieces do require a color printer I tried to make it as solo color printer friendly as I could without requiring any glue. Saving both time and filament printing with few color changes. 

If you print this with unique colors, I'd love to see a photo of how it comes out. For those using the computer to splice, I left a completed helicopter in the background of the file to help visualize how adjustments to the colors will look, I hope it helps.

*Note, I added additional wall loops and infill on the propeller and leg pieces since they seemed a tad weaker in case this is used to be disassembled often, but if you have very young or energetic children might be best to add even more additional loops or infill to such pieces.
