I only have the old version (2164) without the top cone (very small hole instead), it is quite "round" at the innermost ring...
you could add one edge prim (for connecting only) just outside the dome, could make connecting easier...
is it already subfiled? can be used for both variants, the old one has a 5mm shaft (conical to 5.5mm at the top for unmoulding)
total lenght 55,8mm, top hole 2mm
