So I searched desperately for it in our quite crowded living room..........nothing good. So I picked up some courage & used the little round thingy in keychains to scratchbuild a new one . Luckily it turned out quite well for my first scratchbuilt part! Well, just thought of telling it to you so I can share my learning experience.
MORAL for this event: Keep detached parts away while modifying/realigning.
