The spiders I created came out well on the Milling however I was planning pewter casting with it and the pewter might not fill all the legs as it will flow in one direction it wont roll back into the back legs. I think I was thinking too much about getting the manufacturing stage correct and should have taken more consideration of the design I created and whether I was creating something which would work.
I changed my design to something which would work better for pewter casting, I also went a bit further with my new design and created 3 different depths to cut down into on the machine to experiment with the settings and make my design more interesting.
