Remix of Flippy the Robot

thingiverse

This is a cool design modeled after YouTube videos I mentioned.\r\n\r\nI initially remixed this to fit my battery case I was using. When I received the battery case, it was actually pretty close to the original designer's case. While changing the design, I decided to make the legs more 3D rather than flat sides. The first version of those that did not have a base, the idle arms had a tendency to catch under them. The second version of those legs, I added a 1mm bottom and made the rest hollow. I didn't have an M3x32mm bolt, but I did have an M3x35mm bolt. That was actually a little too long and probably would catch one of the idler arms, so I used two wire ties put together. The wire tie idea comes from the Hungry Bot design.\r\n\r\nThis is the motor I ordered and the battery case. The battery case measures 63.8mm Long x 25.5mm Wide x 15.6mm High. In the FlippyBody_Mod_Rev45.scad file, you can change the Bat_Ht = 15.6; to the height of your battery case if it is a little different. The length difference should not matter much, but the width might.\r\n\r\nI left off the connector pin after using it in the first version I tested. The battery case keeps it together quite well in that area by being a snug fit. I would like to do away with the M3 screws and use M6 3D printed plastic bolts like gzumwalt's hummingbird uses, but will have to make the body just a little bigger if I do that.\r\n\r\nI added some pictures of how I put it together and a short video of it. As you can see from the video, those pyramid-shaped legs help to keep it upright. They worked better than I thought they would.\r\n\r\nVideo of this in action is available here.\r\nWhen putting this together, make sure you have the battery wires on the inside of the idler arms before super gluing them in place. I did that, but was able to maneuver the motor and battery case out and readjust that. I marked the motor's + and - on the motor for reference. I just wrapped the wires around there temporarily when checking for correct ones to use.\r\n\r\nI included the STL files in pairs for simpler printing. There is also an OpenSCAD file for each of those STLs along with an Assembly OpenSCAD file to show how they all go together.\r\n\r\nI would print one of the sides from FlippyBody_Mod_2x_Rev45.stl first to check for fit of your motor and battery case. You can split the two parts apart using Slic3r Prusa Edition and be able to print just one of the sides. If you are using the previous design, the pyramid-shaped legs in this design should fit that one also.
