Summary This eight sphere design contains extruded non-symmetrical spirals and loops. A central sphere is raised and pierced in the center of the sculpture. Print Settings Printer: QIDITECH Dual Rafts: No Supports: No Resolution: .1mm Infill: 20% Post-Printing Acetone Vapor Bath I use a glass jar with acetone, set into a rice cooker with water to warm it. This generates acetone vapor to smooth and shine the surface. How I Designed This 3D Design I used AutoDesk Flex360 to design this. The basic sketch was circular, then I repeated it 7 times to make a flowerlike design. I selectively extruded portions of it, then used a spere to reshape the top. I added a sphere in the center, which is hollow, and has a seven-sided hole in the top.
