UPDATE 17/02/2023 Added a sanding aid to sand the inner edges of the outer surface of the lampshade after the filling primer __________________________________________________________________________________________ UPDATE 18/02/2023 Added a holder to hang the shade from ceiling for spraypainting it.

As soon as everything is prepared, the mold is simply assembled with M8 screws and nuts and the master model is filled with silicone on the inside. After the silicone has hardened, the mold is simply unscrewed, the master model is removed and can then be filled with plast
