A weak spot of the original model is the window holding the spring end, whose borders may break if the spring is under high tension. In this remix I increased the wall thickness at these places by slightly reducing the window size.
It will fit for springs that are up to 4mm wide at their widest point, and up to 2mm wide at the narrowest point.
Use it together with the other parts in the original, the remixed part is fully compatible.
Update v2 - 26.10.2025
To make it even stronger I also increased wall thickness (by reducing the space for the spring a little).
