DJI - LEGO Adapter

My son found a pack of spare rotor blades from my DJI Mavic 3 that I don't have anymore. He asked me if he can use it for a Lego buildup. After 2 minutes he came back and told me that it doesn't fit (surprise) - but what does a brave father? In about 7 iterations (because it's all so small to measure - so try out was more fun) I designed an adapter from DJI rotor blades to Lego cross hole - like the Lego motor has.

Just put the rotor into the adapter and turn it to fix the two parts together (bayonett connector)
I also uploaded a tighter fit on the middle-cross as my first print fits nicely but next print was loose to put on.

For any father out there having the same "problem" - but all other people might also use it for sure.

Have fun - I would like to see your prints & lego builds :-)

Greetings & have a great time!
