ArcVase1-update

I used circular arcs to build the basic shape of this part. The photos show the STL file SCALED DOWN TO 50% BEFORE PRINTING because the full size print said it would take 2 days to print. This print took a few minutes more than 11 hours using a print speed of 90 mm/sec and a layer height of 0.200 mm.

I'll add photos of the full size print when it finishes.

2 days later:

I've added 2 photos of the full size print next to the 50% scale print. The full size print took 44 hrs 21 min to print, so most people probably won't want to do this. But scaling it to a smaller size works quite well.
