What is the best way to attach a 3D printed part to a servo for robotics use?
Sounds more like a material/mechanics of materials problem to me. I'm assuming this is an FDM part, and the M3 nut is metal? The nut will have no trouble stripping this. FDM parts are far from 'full ...

tl;dr: use 6 V
Those rascals are rated for 6 volts, not the nominal 7.4 V from 2S LiPos. You could imagine a Shenzhen manufacturer's design/value engineer zealously shaving a penny cost per unit by ...
