Updates! 4/27/17- I've Designed Another Gearbox for This Project. The Ratio is 66:1 - Check it Out on Thingiverse at http://www.thingiverse.com/thing:22771054. 6/17- I Added the End Effector Holder from My Modular Robotic Arm Design to This Project, So You Don't Have to Download Both Files. Printing This Horizontally Can Be a Challenge, Especially with the "Prettier" Version That's Difficult to Get to Stick to the Bed - Good Luck! 3/26/17- I Uploaded an Arduino Sketch That Controls This Project, Which Has Been Improved by Adding Calculations When the Joint Arrives at a Point and Calculates All Angles Before Moving. It Also Moves in a Straight Line Using XYZ Coordinates. 3/18/17- I Revised the Rotating Base, Which You Can Find on Thingiverse at http://www.thingiverse.com/thing:21867163. 3/14/17- I Uploaded the Arduino Program That Controls This Project, Which Uses Inverse Kinematics to Determine the Position of J3 from XYZ Coordinates. 3/12/17- V3 Parts - I Chamfered the Hole Where the Pins Fit in, So There's No Extra Material to Remove After Bridging. 3/9/17- V2 - I Fixed Issues with Too Much Clearance Between Ring Gears and Holders by Making Them .1mm Smaller. The Resulting Clearance is .1mm.
