These are 1/10 scale traffic cones I use with my R/C drift cars. I drew them up to include a realistic looking base for more scale detail.

This was my first attempt at printing multiple colors by pausing the print and swapping filament colors. To get a clean sharp color swap first
pause your print then quickly jog the Z up about 30mm to get the hot nozzle off the part. Then swap the filament color. Purge out about 100 mm to clean the old color out of the extruder and get the new color primed an ready to go. Hit resume print and wait for the next color swap.

I printed these from Hatchbox PLA at 208 deg. on a Printrbot metal simple using Slicer and Repatier host software. The parts were modeled in AutoCAD.
