Convert Logo to 3D STL

This is a test, if it works i will be wanting a lot more done

I have a flat logo image and I need it translated into a clean, print-ready STL file. The finished result should be a full 3D model, not a simple relief or 2D cut-out. Because the piece is only meant to serve as a prototype, I’m happy with basic surface detail rather than intricate engraving—clean edges and accurate overall form matter more than tiny textures.

Key points:
• Deliverable: one watertight STL file that opens error-free in Cura/PrusaSlicer.
• Scale: roughly 80 mm wide (I can resize later; just keep proportions consistent).
• Printability: no overhangs beyond 45° and wall thickness of at least 1 mm so FDM printers handle it easily.

I’ll provide the logo in PNG and SVG formats as soon as we start. Let me know if you need reference dimensions or a quick sketch of desired depth. Once the file passes a quick mesh check on my end, the project is complete.

This is to be used as a mould for concrete so there needs to be a back and front or a hole at the bottom to pour the concrete into
