![]() Select Filters -> Remeshing, Simlification, and Reconstruction -> Uniform Mesh Resampling. It will look ugly, but don't worry, this is going to be the inside and nobody will see it. Hit apply and Meshlab will simplify the model. Enter something much smaller like 25,000 faces and check "preserve boundary" and "preserve normal". It should show the current number of faces and you can enter the target number of faces. In Meshlab, select Filters -> Remeshing, Simlification, and Reconstruction -> Quadratic Edge Collapse and Decimation. įirst we're going to hollow out the model. I learned how to do this using the excellent directions provided here. It will also reduce the weight, and will let light shine through more easily. This will reduce the cost and time required to 3d print the ornament. Now we're going to edit the file to make it hollow. Select File -> Import Mesh to import the STL file you downloaded. Download this file and it will be our base.ĭownload and install Meshlab from. I started with the smallest file, since it's already more complex than our final piece will be. You can find the Lincoln mask available for download here in a variety of sizes: And although it looks like he was bald at the time, he actually had a full head of hair - it just wasn't captured in the mask. In case you're interested, Smithsonian tells us that the mask was created from Lincoln's face by sculptor Clark Mills on February 11, 1865, a day before Lincoln’s fifty-sixth birthday. I started with a 3d model provided by the Smithosonian Institution, a "life mask" of Abraham Lincoln. But you can always get it printed by your favorite 3D-print-on-demand service. Obviously if you want to print it yourself you'll need a 3d printer. Tinkercad (It's free but you'll need an account): Thanks to THE INTERNET for helping me figure this out and provide free and open-source software to get the job done quickly! Special shout-out to this page for helping me with a nice "hollowing" process. I thought this would be a nice way to teach myself the required workflow. ![]() I've developed basic models for 3d printing before but not starting with something organic like this. What better place to start than with Abe Lincoln!? You can hang this on the tree and if you print it in a translucent plastic, you can put a christmas light into the bottom and it will light up. In this instructable you will learn how to make a simple ornament for 3D printing, starting from a complex 3d model of a head.
