![]() ![]() If you use chains with 4.5 diameter balls, you should use new motor wheel(15.5motorwheel 4.5ball)īut you have to use your own initiative and open the way for the chain to pass for this size of chain (4. I also put these two pieces for download. Chains are usually 3.2 mm in diameter per ball But if you want to use metal chains, you have to change a number of parts according to the size of the chain balls. To get a much better result, please use metal chains. I designed a cover chain into weight for Hold the chains on the motor wheel tight. If the bearing with an inner diameter of 3 millimeters and an outer diameter of 6 is not found, you can use other sizes that only have an inner diameter of 3 millimeters. If you do not have a shaft, you can cut it from the flat part of a metal hangerīe sure to use ball bearings for easy and smooth rotation of the shafts In many places metal ball chains are very rare, so I used (plastic ball chains with a diameter of approximately five millimeters per ball) EJW 3D-printed clock.zip includes Autodesk Inventor files and solid model exports (stl and sat files).HI everyone.This mechanical clock was previously made by two smart guys ( A26 and krahut) and I assembled it into a collection with small changes. I've included the complete CAD files from the escapement shown here, so you can use my models as a starting point for your own creations. Hundreds of years before the introduction of true animation, people all over the world enjoyed shows with moving figures that were created and manipulated manually in puppetry, automata, shadow play, and the magic lantern. The colors, the compactness, mechanical switches, and satisfyingly simple but. Obviously, nice escapements and clocks can be built by hand, and I encourage anyone mechanically-minded to at least visualize how escapement works, if not trying to build one yourself. Cool Simple 3d PrintsThe best 3D printers Formlabs Form 3 Lulzbot Mini. ![]() The bed size of the Statasys (about a cubic foot) prevented me from building much larger versions of this escapement where the tolerances wouldn't be as much of an issue. The weight, which is out of the video frame, is connected to a spool on the center of the escapement wheel via a white string that is almost in visible in the video. In the video, I have quite a large weight pulling on the escapement wheel and the pendulum moving briskly, but if the pendulum loses just a little bit of energy and doesn't make a full swing the escapement wheel doesn't lock, and instead, spins freely dropping the weight. While it did work, the tolerances on the one shown were not quite good enough for it to work consistently. The escapement proved to be the biggest challenge. I printed working gears, springs, and escapements in my attempts to test out each of the required components. I imagined that after dissolving away the sacrificial material, you could wind the clock up and have it start ticking. I was big on clocks, and was trying to design a fully 3D-printable clock. This project dates to 2001 when I was at the MIT Media Lab. With careful design, you can create captured moving parts, like the interlocking gears shown in the Slideshow. The hot noodles are printed layer-by-layer and fuse together building finished-quality-level parts. ![]() The Stratasys FDM works by laying down "hot noddles" of ABS plastic and a sacrificial material that can be dissolved by water. These are the basic components of a clock 3D-printed by a Stratasys FDM 2000. ![]()
