6 Helix wine cork holder with a letter projecting up (and down) from the base. If you look underneath you will notice this can double as a wax stamp. For customizing you will need FreeCAD, a free and open source CAD program available at http://www.freecadweb.org.My best results were printed at 97% scale, 3 shells, low infill, ABS @ 245C. To customize with your own itinital, check the screen shot - you can use FreeCAD to change the parameter for "Text String" in the area shown, and you will need to put in the path for the font file you wish to use. Depending on the letter you may want to make the text a bit smaller - simply change the size above where you enter the text string. If you need to move it, you'll have to go up the tree one level and click on "Custom Text," switch to the data tab at the bottom, expand Placement, then expand Position, and move the X and Y coordinates slightly to center your new text. To export, select the 'Wine Cork Holder" and "Custom Text" (not the caps one) at the same time and select Export... from the file menu. Then select Mesh Format, and enter your file name. the STL extension is the default for mesh formats.
