I've been busy with the 3D printer lately. Seems like the winter time is when I use that thing the most. We found on Thingiverse an STL fille for an LED traffic cone. I made one to see how it looked. I had black PLA loaded into the machine, so that's what I used. I rather like the look of the black cones & will make more of 5, or 6 more of them. The flashing lights make them great for marking the dumpsite when we work nights in the sand & gravel mine again.
