Cover cap for “Maco” window hinges. I couldn't find them for sale anymore, so I recreated their design. They're not identical to the originals, but they're close enough. For the top-hinge-cover I added some discs to prevent it from coming off the bed. Also, the top-middle-cover needs to have its inside corners cut after printing (see the last image).

Please be careful when removing supports, the models are very thin and they break easily.
