1/10 traffic cone I drew on Sketchup copying a cone from work. Clips together easily after a tiny bit of fettling with a sharp knife. I printed coneb.stl in black, conew.stl in white and coneo.stl in red (didn't have orange). Base is 42mm square and whole thing is 75mm high.Think I had the start temperature a bit high on the pieces in the photos as I have a bit of elephants foot going on. Pieces will line up perfectly if printed correctly.
The larger piece in coneo.stl has a 0.8mm wall thickness to speed up printing so print with single perimeter shell, if that is a problem I will produce a chunkier version.
