Coaster mystery

pinshape

Something about the earth being round is pretty fascinating. People have been wondering how they discovered that the earth is a sphere for ages now. I think one of the ways they figured it out was by looking at the moon. This download comes with two drink coasters, a positive and negative one. You can use these to place your favorite drink on them. If you printed it out, don't be shy about showing off your skills and uploading a picture of it. This is a standard-sized coaster that measures 100 by 100 by 5 mm, which fits perfectly in my coaster holder: https://www.thingiverse.com/thing:3130397 I printed this model using Fillamentum luminous green PLA. I used a layer height of 0.25mm and an infill percentage of 18%. I also used a nozzle diameter of 0.4mm with my extruder set at 210 degrees Celsius. I used a heated bed to ensure the best results possible. To avoid curling up at the bottom, I added a brim to it. Don't worry if you want to use your own configuration; it's completely fine! Design stages: I picked a logo from my browser and saved it in SVG format using Inkscape (see video*). Then, I opened the SVG file in Blender and turned it into a 3D object. In Meshmixer, I repaired the file by clicking on the 'Inspector' button under the 'analysis' tab. I also added a drink coaster to the model in 123D Design using simple modeling techniques. You can choose to make a template of a drink coaster in another program, such as Tinkercad. Then, I merged the drink coaster with the 3D model after scaling it in Meshmixer. In Meshmixer, I created the 'positive' file. For the negative model, I used 123Design to subtract the file from a drink coaster and saved it as an STL file. I sliced it for printing, but the model still had some issues even after repairing it in Meshmixer. So, I decided to export it into Netfabb Online Service, which is a free STL repair service. After that process, I previewed the model in my slicer (which I highly recommend doing before printing a model). The preview looked great with perfect lines; so I could print it without any problems.
