Deebot OZMO Main Brush Motor Coupling

I lost the square plastic part/cap that joins the Main Brush Motor to the shaft of the Main Brush when I was cleaning

I didn't want to buy a whole replacement kit so I thought about designing this that closely resembles the little cap that goes on the end of the Main Brush shaft

Hopefully it helps others

Note: You may need a little bit of sandpaper on the 3D printed cap for a good fit

I have been using this replacement for 2 full house runs at the time of writing and no issues (will update if there are any). Used PLA, ABS would probably be more durable
