>>7133392I guess because it worked in LDD when they designed it meant that they didn't put much thought into the actual thing.
Same thing happened with the ammo holders on a bunch of G2 Bionicle figures.
That axle can be pushed through in LDD and simply clips through the CCBS bone while on the actual model it pushes the black Technic piece outwards, stressing the pin that connects the piece to the bone.
