VoronoiBowl2A
This is VoronoiBowl2's basic geometry, but with the ribs changed to circular cross sections. With this change I was able to eliminate all the sharp corners which resulted in a more organic look. Printing is still a challenge for prime/retract/stringing and bridging. This part printed in 26 1/4 hours @ 0.200 mm layer height.
Photo's 2 & 3 show some problems with the print. I'm not sure what caused these - it might be that the overall structure was not strong enough to hold the part 100% still while it was being printed.
The good news is that by changing prime/retract from 5 mm to 6 mm I was able to eliminate almost all stringing.
