This document provides step-by-step instructions for assembling a DIY postcard press kit from Stampomatica. It involves joining small metal and wooden components using threaded rods, nuts, and an Allen key to construct the base, sides, and lever system of the press. Paper and a 3D printing plate are then placed inside, color is rolled onto the plate, and the levers are pressed together to print the design onto the paper. The finished postcards can then be shared on social media.
