Summary

Hi,

Simple and elegant design, easy to print and assemble, this toy is great.

But I was a little disappointed by the altitude reached by the flying propeller.

So I tried to improve that, and succeeded !

For this, I enlarged pull rod and totally redesigned Flying Propeller.

My flying propeller is slightly heaver than original one, but the extra weight is located on the peripheral ring. This gives inertia to the propeller.

The longer Pulling Rod make any propeller fly higher (compared to original pull rod)

Some more infos :

Original pull rod is 240mm long and has 73 teeth

Modified one is about 320mm long and has 100 teeth ! )

This gives 37% more teeth

Of course, it had to be printable (in one piece) on my 3D printer, which has a standard size heatbed (250 x 210mm)

Most 3d printers should be able to print it.

For information, the creator of this great toy made 3 versions of Pulling Rods

• Classic
• Hook
• Ergonomic

I started from the « Ergonomic » version, because this is this version out of the three ones which can be the longest. The reason is because the handle prints separately.
