H960 blank panel clips

The sharp transition will concentrate any stress, and a radius will reduce that. I'm not sure how much difference it makes for a 3D-printed object but it would be significant for injection moulding. The lack of any radii is actually part of the problem with the original, and the breaks always occur right either at the sharp transition between post and flat surface, or more often between post and ball. Secondly, and maybe less importantly, to make the lower part (maybe half the length) of the post a slightly smaller diameter - but not to the extent of reproducing the ball-on-a-thin-post of the original. This eases alignment, because as Al pointed out, the panel always tilts or twists as it's removed and that puts a bending strain on the joint - in this case, now at the post base than than just below the ball. Maybe that post should be a short spring ;-) -- Pete Pete Turnbull
