Big flying butterfly

Large flying butterfly, for hanging on the stroller

Maybe it's not directly an improvement of the stroller, I used a hook to hang the toy there, but your children will probably enjoy such a flying butterfly

To connect the parts, I used 2 pieces of M3x60 screws to attach the wings, 4 pieces of M3x20 to connect the arms with the hinges and 2 pieces of M3x6 to connect the hinges and the wings. I recommend using M3 self-locking nuts to prevent the screws from loosening.

I used an M3x5mm worm to define the range of movement of the wings

For the safety of the child, check the edges of the wings, if they are sharp after printing, round them off.
To make the wings move up and down, hang a rubber band about 30 mm long on the hooks of the wing holder.

I recommend hanging the stroller canopy on the frame, the hook fits the tube diameter 23-26mm
For the color version of the wings, I added g-code with a filament change

Because I already have an older child, I have to find a stroller for the photo shoot

I was inspired by another model of mine where I used similar moving butterflies:
