Hi, you can achieve this by converting the OBJ model, which can be exported now by the browser version of EasyEDA, to a STL model by using an online converter like e.g. [https://www.ofoct.com/3d-model-file-for-3d-printer-converter/3d-model-file-converter.html](https://www.ofoct.com/3d-model-file-for-3d-printer-converter/3d-model-file-converter.html). Currently, the model is exported in imperial units and with a PCB thickness of 2.54mm. To transform this into the metric system (mm) and to 1.6mm thickness, you can use my quick-and-dirty converter written in C# for cs-script. The converter works only with the text version of STL files, not the binary ones. The converter will "create" an origin at the lower left corner of the PCB. ``` using System; using System.Collections.Generic; using System.IO; using System.Globalization; // Compile to a console executable using cs-script. ([https://www.cs-script.net/](https://www.cs-script.net/)) class Script {     static void Main(string[] args)     {         if (args.Length.Equals(2))         {             if (File.Exists(args[0]))             {                 ConvertStlFile(args[0], args[1]);                 Console.WriteLine("Done.");                 return;             }         }         Console.WriteLine("Usage: EasyEDA_3D_Correction <Source STL file> <Destination STL file>");     }     static void ConvertStlFile(string SourcePath, string DestinationPath)     {         string[] readText = File.ReadAllLines(SourcePath);         string[] writeText = new string[readText.Length];         int i;         // Find the coordinates of the lower left corner of the PCB         double min_x = 1e12;         double min_y = 1e12;         if (readText.Length >= 65)         {             for (i = 0; i < 65; i++) // the first 8 facets contain the PCB outline?             {                 string[] token = readText[i].Trim().Split(new char[] { ' ' });                 if (token.Length > 0)                 {                     if (token[0].Equals("vertex"))                     {                         double x = 0.0;                         double y = 0.0;                         if (double.TryParse(token[1], NumberStyles.Number, new CultureInfo("en-US"), out x))                         {                             if (double.TryParse(token[2], NumberStyles.Number, new CultureInfo("en-US"), out y))                             {                                     min_x = Math.Min(min_x, x);                                     min_y = Math.Min(min_y, y);                             }                         }                     }                 }             }         }         for (i = 0; i < readText.Length; i++)         {             writeText[i] = readText[i];             string[] token = readText[i].Trim().Split(new char[] { ' ' });             if (token.Length > 0)             {                 if (token[0].Equals("vertex")) // only vertex lines contain coordinates                 {                     double x = 0.0;                     double y = 0.0;                     double z = 0.0;                     if (double.TryParse(token[1], NumberStyles.Number, new CultureInfo("en-US"), out x))                     {                         if (double.TryParse(token[2], NumberStyles.Number, new CultureInfo("en-US"), out y))                         {                             if (double.TryParse(token[3], NumberStyles.Number, new CultureInfo("en-US"), out z))                             {                                 x = (x - min_x) * 0.254; // move to X-Origin and scale to mm                                 y = (y - min_y) * 0.254; // move to Y-Origin and scale to mm                                 z = z * 0.254; // scale to mm                                 // 1.6mm board thickness instead of 2.54mm                                 if (z > (2.54 - 1.60)) // everything above the top layer (1.6mm)                                 {                                     z -= (2.54 - 1.60); // move down                                 }                                 // replace STL line                                 writeText[i] = string.Format(new CultureInfo("en-US"), "  vertex {0:0.000} {1:0.000} {2:0.000}", x, y, z);                             }                         }                     }                 }             }         }         // Store converted STL file         File.WriteAllLines(DestinationPath, writeText);     } } ```

@MikelSim Thanks for this cs-script. Although when I import the stl file that comes out of the conversion to tinkercad, I still don't see a board outline. Any help would be greatly appreciated.

@Willem Burgers on Windows you can just open the *.obj file with integrated "3D Bilder" and then save as *.stl (and also reposition the origin). In OpenSCAD import with `scale(0.254) import("YourPCB.stl");`.
