Robot figure with flexible joints (parametric, OpenSCAD)

thingiverse

This futuristic robotic figure utilizes old-fashioned screws for its flexible joints, letting them cut their own threads instead of using nuts.\nThis cutting-edge robot draws inspiration from http://www.thingiverse.com/thing:331035.\nPost-Printing\nPrepare all holes for screw placement\nThe model is designed with M3 screws in mind, but some holes may come out slightly too tight due to the common issue faced by FDM printers when creating small holes.\nUsing a drill, enlarge the holes where threads need to be cut to a diameter of 2.5 mm.\nWhen installing a screw that needs extra space, use a 3 mm hole size.\nFor this user (utilizing PLA) no additional tools were necessary for thread cutting, but others might find a specific thread cutter helpful.\nThe screw hole size can also be adjusted as a parameter within the robot.scad file. Look for "screw"-related parameters in the OpenSCAD file for more information.\nDesigning This Model\nOpen the OpenSCAD file "robot.scad"\nThe figure is designed with flexibility in mind, and multiple parameters at the top section allow for easy adjustments.\nParameters such as torso-sizes ("torsoX", "torsoY", "torsoZ") serve as base measurements from which other values derive.\nFor example, changing the "torsoZ" value will proportionally alter arm and leg lengths.\nOpenSCAD-renderings for different torso sizes are available to view.\nTo speed up rendering times, users may want to reduce the quality settings ("$fn" and "cornerQuality").\nAlso, feel free to customize your own text on the robot by referencing http://www.thingiverse.com/thing:96714 for tips on creating personalized fonts.\nWould you like something truly customizable?
