Tulsa Open Source Hardware Coaster

thingiverse

I created a small project for Tulsa Open Source Hardware group (https://groups.google.com/forum/#!forum/tulsa-open-source-hardware). It effectively prevents condensation on cold drinks placed on my desk at work. I recently added a derivative section, which I thought I had included earlier. To use it, simply print the 'toshw.stl' file and place your cup on top. You can customize the coaster by modifying the scad files and regenerating them.
