Today was more 3D printing, printing out the same designs as yesterday but out of PETG plastic. PETG plastic is a heavier and is a lot stronger the PLA plastic used yesterday. After the 3D printing finishes over the long weekend, the final testing with the instron will be completed. While the parts were 3D printing, I spent my time refining a new CAD design- hoping to fix the flaws of the previous designs.
