egg beater bolt connect to M4 screw (only bolt)

thingiverse

I have designed this simple egg beater for daily life. It is very powerful if you choose a good egg beater head. If you don't have an egg beater head, why not make one yourself? I use a soda drink plastic bottle to make a simple one. It works very well even better than that I brought from the 100 Yen shop. The long nut has also been modified that can directly connect to the M4 bolt. All the other parts are the same as the last one. Hope it will give you some help. https://youtu.be/vr4WaPHmefM
