About the tabs ...
In the building instructions, I note that the tabs should be pasted on thin cardboard, and that's why the lower Support Formers are a little bit narrow so they can fit between the thick tabs... I took that into account in the design of the bottom Support Formers .
I hope that thin tabs you are using, will not cause you problems adjusting the body parts to the supporting Formers inside.
you can look here.
