Watertight Spiral Vase

myminifactory

I've printed several vase-like parts before, and every single one leaked when I put water in them. This makes such parts far less useful than if they were actually watertight. This new part has double walls - excluding the spiral ribs which are purely decorative - and each wall is built with 4 loops. The bottom is also double walled, with each surface made up of 4 layers. The second photo shows what a layer height of 0.300 mm looks like. Normally I use 0.200 mm, but I wanted to see if increasing this would help reduce total print time without compromising the quality. The final result isn't as good as 0.200 mm, but it's still acceptable. I used Craftware to slice the part after running the original STL file through 3D Builder to correct any errors. Total print time for this part was 11 hours and 11 minutes.
