Awesome sundial and fun video feat. UM2

Recommended Posts


I have been trying to print the sundial using blue MakerGeek PETG. I don't get stringing but the fine hair. Also as you see in the pictures there are sections that are 1mm wide and 6-7 mm wide. I am having trouble making the bridging work. It fails in the center. Temp 225, B/P 70, speed 30, layer .2 mm, retraction 4.50/30. What changes can I try to improve the bridging with PETG?

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
