Fourth day at 3-D printing camp, and continually developing and progressing through the stages of 3-D printing. One project developed today was a miniature Parthenon on Tinker-cad. Then this project was uploaded to Thingiverse as part of the Thingiverse challenges in the art category. Also, designed was a phone case including the anti-possession symbol from Supernatural. While neither of these were printed, it still provided the benefits of mastering Tinker-cad and further developing skills in the 3rd dimension.
