Parametric Christmas Ornament Ball

thingiverse

This is a customizable Christmas ornament. It has an internal hour-glass structure for support at the top, and it looks kind of cool. I printed it without fill, making it 2" in diameter. You can add your own text, but it didn't come out very readable on my first print. It took 2 hours and 1 minute to print on my Makerfarm 10" printer, and it weighs about one-third of an ounce. To use the write function, you'll need the write.scad file from http://www.thingiverse.com/thing:16193. I was inspired by http://www.thingiverse.com/thing:579333, but the walls were too thin to print well on my printer. Instructions: Print the STL file or customize the .scad file. On my second print of this, I added 3-4mm beads to the inside of the hour glass at about 12mm up and again at about 43mm up.
