Couldn't sleep thinking whether I have messed up sth.@Flitedesign 3d It seems there is a minor issue in the plans.
Formers EF1/2 (both, foam cut and 3d printed version) do not fit into ES4. If EF1/2 alignment tabs are put into ES4 cutouts there is plenty of space at the bottom (see pic 1).

If the formers EF1/2 are aligned with ES4 then either side of the cutouts is too high.
(see pic 2+3)

First I thought I messed up the printing scale. But I measured 3x and reprinted @100% scale.
EF1 "circumference" is ≈17.3cm.
ES4 "circumference" at EF1 position start to end is ≈18.5cm
Same effect is at EF3. If aligned with the inner side of ES4, the radius of EF3 would be too small to have ES4 ending up correctly on the outer side...

Now I could move the cutouts 0.6cm lower on each side.
Alternatively the space at the bottom could be filled by additional material on EF1/2.
But I am afraid this has an impact in the thrust line, hence, your advice would be much appreciated!
But here are some more pics highlighting what I mean:
EF1 circumference from lower end of the alignment tab to the other side is 14.1cm.
ES4 distance between inner side of alignment tab cut out is 15.1cm (tried to incorporate the curve as good as possible).
Have not made the EFx formers "thicker" but removed about 1cm from the ESx middle sections.
Now it fits.
