glucose molecule 3d model

Create a 3D printable model of a glucose molecule (C6H12O6) using completely flat, circular atoms. Each atom should be represented by a solid circle (not a sphere), all lying perfectly on the same plane as if printed directly on a flat surface. The circles should be slightly extruded upward by the same amount (very thin height) to make the design printable. Connect atoms with flat rectangular bonds, also at the same height. The overall design must stay entirely flat, with no raised or floating parts. Use distinct sizes for carbon, hydrogen, and oxygen atoms, but keep all of them flat and coplanar. Output a watertight STL file ready for FDM 3D printing.
