This jar was designed specifically for 90mm props. With it, you can take this toy on a picnic without fear of damaging these delicate things. You can print parts for any propeller quantity - 4, 7, 8, 10, 12... 16, 18... 24 and so on. To strengthen the joints of the extenders, you can use transparent PU glue like B-7000.

The best result will be when printing walls with a thickness of 0.8 mm in vase mode. Make sure the filament's melting speed is not too high to avoid printing gaps. PETG recommended, but you can use others.

The composition of this set:

• jar base (bottom) for 4 propellers
• extender for 3 propellers
• extender for 4 propellers
• jar lid
