My printrbot jr. doesn't have that capacity to print the large backbone from Anandromeda's design so i designed my own. I have made som changes to the design as you can see.Link to first steps: http://www.youtube.com/watch?v=aFz1aFTiWMEPrint both parts, use 30% infill and support. Glue the parts together. The holes for mounting the hip is 3mm, so you will have to drill the holes in the hip part's and use long m3 bolts to secure the hip to the backbone.
