Dometic Seitz S3 S4 Window Opener Click Clack Clip

thingiverse

A common problem with this model of Domestic / Seitz S3 / S4 windows is that you inevitably lose the clips for the spring and steel ball when you fail to notice them. To overcome this issue, I designed a replacement clip that can be secured using a cable tie. The cable tie should be applied as shown in the picture or wrapped completely around the clip if there is sufficient space available. For the metal parts, I used a 4mm steel ball from a dismantled 608 bearing and a pen spring to replace the original components. Fortunately, this setup has eliminated the risk of losing the clips again. While it would be ideal if the spring was harder or stiffer, for now, it effectively holds the window open in still air conditions.
