I need a clean 3D model of a round coin that prints reliably on an FDM or resin machine. The coin must be exactly 22 mm in diameter, include a slight raised lip around the perimeter, and feature my text-based logo recessed or embossed in the centre. I already have the logo artwork as a JPEG, so you’ll simply trace or convert it and integrate it into the coin face—no logo design work is required. Once the model is finished, supply the final file as an STL (and the source file from your preferred CAD package if possible). Please keep wall thicknesses and relief depths practical for hobby-level printers (0.4 mm nozzle friendly). A quick render or screenshot showing both faces of the coin would be appreciated for verification. I’ll provide the JPEG immediately after we start; I’m happy to answer any dimension or tolerance questions so the first print comes out right.
