Solid models of four hinges for entrance or furniture doors. It is supposed to be used for production using 3D plastic printing. Also in the archives are elongated modifications of two of the four parts. Models are created in the SolidWorks program, then imported into STL, STEP and X_T formats. When developing the design, recesses and cutouts were used in order to reduce material costs and decorate the hinges. The holes, which are likely to be parallel to the base when printed, are teardrop-shaped to avoid sagging of the plastic layers.
