Honda / Acura Shift Knob, weighted and non-weighted 10x1.5

Bird head style shift knob for Honda and Acura threads, 10x1.5.

Cavities allow it to be filled with pennies during printing for weight. 

While it doesn't need support to print technically, - you will need it because after you put the pennies in, it is top heavy and is likely to fail. 

I would also use a big brim. 

block any support that would be put in the thread hole.
