When you have thin pieces, the end mills torque is more effective in potentially kicking off your material because its lower and closer to the materials center of mass.Also for small objects, theres little adhesion keeping the bottom surface in place, raising the likelihood of the mill throwing the object off.Thus, its important to design your piece with this in mind.
