The display flex ribbon extends more than the case allows for

[MarkJeronimus]

The Light Edition watch I have doesn't fit (without squeezing) into the case.

I measure that the case allows for a 38.8mm total dimension from the very top of the display (i.e. 18.0mm above the optical center) to the bottom-most extend of the cavity for the flex. When I measure my item, the round display is exactly 36.0mm wide (just as a verifying measure to show that I don't measure wrong) and the total height is 39.5mm. This is 0.7mm too much. Given that the bend radius of the flex is about 0.75mm, this is no small issue. It could probably fit, but it would seriously hurt the flex by squeezing it into a square shape with bend radii way too small.

[edit] I forgot I added 0.2mm margins to the PCB model below. This means the cavity for the flex is 0.5mm too small, not 0.7.

This is a rendering of the STL file, along with a model of the electronics according to my measurements:

Note that the cavity for the flex also seems too shallow, as my flex measures about 1.95mm in thickness (in the model I used 2mm, at line 20)

Best approach to fix this would be with the parameterised model: https://github.com/Open-Smartwatch/3d-files/tree/master/case-light-round-parametric-printed-straps

what if the case itself is designed by subtracting the dimensions of the pcb? If provided with all the necessary data and dimensions, I can provide an elegant solution for this problem without falling in the need of all parameterized modelling. (Finger Crossed)
