s=Stringtest3

When I printed https://www.thingiverse.com/thing:3687368 my printer produced a lot of stinging between the arms and the center column. This happened even after I thought I had my printer settings pretty well dialed in for no stringing. When I posted this info in the Atom2 Facebook page I got some helpful feedback about how to update my settings to eliminate stringing. So I made those changes and to test them made this quite small test part based on the Cactus1 design.

I was pleasantly surprised when the test printed in 7 minutes with not strings at all.The stringtest3 needs no supports and prints well at a layer height of 0.200 mm and a print speed of 80 mm/sec. Note that the bottom of the print is a bit dark because I switched from blue to orange filament and didn't bother making sure all the blue was purged from the printer nozzle.
