This vase is 7 hours in, http://www.thingiverse.com/thing:28050 scaled to max size, printing with E3D black ABS at 250/105 onto glass+kapton.
And another @ 6 hours 50. This one is 297mm high, weighs 79 grams, and is printed in E3D Everyday PLA at 195/75, with 210 on the first 3 layers, using a 0.4mm nozzle. I put the fan at 100% from layer 4 upwards. http://www.thingiverse.com/thing:856894 Very slight lifting at the edges of the bottom spikes: You can see ghosting on direction changes, but it does add some interest in this case. My last print in ABS showed some Z banding at heights that hadn't typically used before, so I took some time to re-oil the vertical linear corner rods and bearings and, while I was at it, did the X and Y too. This has printed flawlessly all the way up, but there's still some really really slight z banding that shows up if you hold the light at a certain angle. I begin to think this is just a feature of the method of manufacture.
