This is a 100x150x68cm box made with openSCAD.EDIT 09/30/2011 : I've added the .scad files in the .rar. The names are in French so I hope it's clear enough. I've made the shoulder and the arm after i've fixed my box size, therefore if you wish edit parameters everything might not realign correctly.EDIT 10/09/2011 : I've cut the bottom part and the shoulder in half to be printed on a Makerbot.You will need two hinge, a standard servo modified for continious rotation , a DPDT, a switch and some screws/nuts.
