Customizable Stackable Coasters
Description
Customizable Stackable Coasters Change the image to use your own logo or graphic. Example images included for reference. Instructions: * Use a app link Gimp or Photoshop to reduce your image to about 65,000 total pixels or less. About 256x256 but it doesn't need to be perfectly square. * Invert the image if needed so that it is a black background. * Optionally, add a 1 pixel radius blur after reducing the image to help make a smoother mess. (In Gimp this is the Gausian Blur under filters.) * Save or export you image as a .PNG * load the OpenSCAD file and change the image_file variable to the path of you PNG image. * Important: Also change the image_pixels variable to be the actual width and height in pixels or your image. Other variables can be adjusted to your liking. * render and save as an STL from OpenSCAD. * Slice and print to taste. Note: sometimes the STL from OpenSCAD directly might not load properly to the slicer. Use a program like MeshMixer to correct it if this happens.
