Prehistoric Art coaster

Note: This model is designed for SLA printers. The detail doesn't fully show up on FDM printers. This is a coaster with ancient rock paintings. Or cave paintings. The oldest recorded animal cave painting dates back around 40,000 years to a bull found at the Lubang Jeriji Saléh cave in East Kalimantan, Borneo, Indonesia.

This coaster is standard size (100 by 100 by 5 mm), designed to fit into my coaster holders: https://www.thingiverse.com/thing:3130397, https://www.thingiverse.com/thing:3547597, and https://www.thingiverse.com/thing:3546596. Design steps: I picked a logo from my browser and converted it to an SVG file using Inkscape (see video). I then opened the SVG file in Blender and created a 3D object. Next, I used Meshmixer to repair the file, utilizing the 'Inspector' button under the 'Analysis' tab. In Meshmixer, I also added a drink coaster. I designed the drink coaster using simple techniques in 123D Design. You can also create a template for a drink coaster in another program like Tinkercad or download one from my website (https://www.thingiverse.com/thing:3542555). I saved it as an STL file and sliced it for printing. Despite some remaining issues after repairing the model in Meshmixer, I decided to export it into Netfabb Online Service. This process worked well after modeling something. Netfabb Online Service is a free STL repair service. After that, I previewed the model in my slicer (something I recommend doing before printing a model). The preview looked great with perfect lines; so I was able to print it without any problems.
