Using OmNomNom to 3D print scanned images Use these instructions to create a 3D printable file from a scanned image, using pixelmator, OpenSCAD, and MakerWare. Edit the image You can use your favorite image editor, in this case we are using pixelmator for the mac. Rotate the image if needed. If needed, rotate the image. Crop the image as needed. Crop the image so only the desired area remains. Use levels to adjust the image Your goal is a nice black and white only (2 color) image. Most image editing software has a levels feature. Apply levels In Pixelmator, drag the levels onto the image. Adjust levels as needed Notice the resulting image - high contrast, only black or white. Export as jpg Save the .jpg Export as jpg Open image in OmNomNom Drag and drop image to open. Keep size Settings For this project, we will use 2 levels with a width of 443x165 Export as Logo Export as a logo The object will open in OpenSCAD Hit F5 (on some macs FN+F5) to see the preview Editing variables reduce surfaceheight to 2 Editing variables To make getting the proper size simpler, we will remove any border by changing the baseWidth multiplier to 1 instead of 1.2 Preview and render the model F5 to preview, then F6 to render. Rendering might take a while. Prepare to wait By a while I mean 10-15 minutes. Export as STL Prepare (slice) your file for your 3D printer In this case we'll be using a MakerBot Replicator 1 Dual and using MakerWare to slice our model. Scale object as needed In this case, the ruler is approximately 7.75 inches, so the setting the X value with uniform scaling on will result in the proper size. Final scaled object. Click Make to export your file. Export to file We use a raft to make removing the object easier. Be sure to adjust your settings for your specific 3D printer. Print and enjoy!
