My Xiaomi Yeelight Desk Lamp that I ordered in Gearbest didn't came with an EU power supply, but with a cheap adapter that always was disconnecting and falling off.
So I created this bracket that holds power supply and adaptor together and it's almost strong enough to pull and disconnect it from the wall outlet (almost). Anyway it works fine and avoid inconvenient plug-offs.
0.3mm layer height, 30% infill. GENERATE SUPPORTS EVERYWHERE (buildplate and also piece).
