<h2>Summary</h2>This is my second clockwork design. It took just under a month from starting the design, to posting it. I modeled it after a Cabestan Triple Axis Tourbillon, which they offer in their high-end watches, and spent many hours looking at Youtube videos of the watch.Similar to the Gyrotourbillon, I tried to make the model an accurate (scaled up) version of the original Cabestan mechanism. I printed the screws to scale, then stuck a 2mm screw in their centers to hold it together. I also included Incabloc shock absorbers by printing clear red 'jewels', and working snap rings to hold them in place.This model is small, about 140mm in diameter. I power it with a 2 Amp USB power supply. Here a real-time video. <a target="_blank" href="https://youtu.be/Imm3mrR06tc" rel="nofollow noopener">https://youtu.be/Imm3mrR06tc</a> This designed moved so fast that a timelapse of it was just a blur. To keep more up to date with what I'm doing I have an Instagram page @mcmaven.pdx, where I'm posting some of my 3D printing and other designs that I haven't posted here. I posted the pulley versions of the L3 Inner Bearing Race (L3 Inner Bearing Race 2a,STL and L3 Inner Bearing Race 2b.STL) and the Stepper Pinion.STL file.Apparently I had the L3 Inner Bearing Race STLs for the gear driven design, and the Stepper Pulley.STL for the rubber band driven design.In my original design, the L3 assembly was gear driven, which is still illustrated in the notes. Gear drive worked fine for the Gyrotourbillon design, but I was having lots of problems finding the correct stepper speed for this Triple design. Too fast and the whole thing would bind up, and too slow, it would intermittently stop. A friend suggested using a rubber band, which led to the version that you see in the video.I would recommend using the Pulley/rubber band approach. That is, print the L3 Inner Bearing Race 2a.STL, L3 Inner Bearing Race 2b.STL, Pulley Brigde.STL, and Stepper Pulley.STL files.However, the L3 Inner Bearing Race a.STL, L3 Inner Bearing Race b.STL, and Stepper Pinion.STL files are included if you want to experiment with a gear driven design.My argument being that the rubber bands provide two benefits. 1) The stepper can be set at a slightly higher speed than necessary, and the rubber bands will slip on the pulley if it is not the perfect speed for the movement, and 2) the rubber bands provide a constant tension, which works well with a movement that periodically locks its position while the balance wheel swings back and forth. If you turn the L3 turntable manually, you can feel the intermittent motion that gets transmitted to it by the escape wheel movement. The rubber bands stretch while the L3 rotation is locked, and contract when the escape wheel turns. Basically acting like a weight would, in weight driven design.Both drive versions are now included if you want to experiment with a gear driven design. I was concerned that using supports would make the bearing race too rough, so the L3 Ring Gear is printed as two parts (a and b), then glued together so you don't have to use supports.&nbsp;Read the Triple Axis Tourbillon Build Notes PDF in the files for more information.Enjoy, McMaven<h2>Print Settings</h2>Printer Brand: PrusaPrinter: <a target="_blank" href="http://amzn.to/2rqZ6Uo" rel="nofollow noopener">i3 MK3</a>Rafts: NoSupports: YesResolution: 1.5mmInfill: 20%Filament: <a target="_blank" href="http://www.amazon.com/s?url=search-alias&field-keywords=Hatchbox+PLA" rel="nofollow noopener">Hatchbox PLA </a>Transparent Red, Black, Gold, Silver

I have no control to moderate or remove these third party print profiles.</li><li>This model may not fit all ESUN cardboard spools. Please review the photos and spool measurements before printing.</li></ul>Description:&nbsp;This adapter system wraps the edges of an ESUN 1kg 199x62mm cardboard spool in order to:<ul><li>provide smooth rotation within a Bambu Lab AMS</li><li>prevent carboard debris from depositing within a Bambu Lab AMS</li></ul>Features:<ul><li>Reusable</li><li>ESUN nameplate for easy identification when reusing</li></ul>Instructions:<ul><li>Measure your spool first to ensure it matches the specified dimensions</li><li>Print this model twice for a single spool</li><li>Affix one spool ring adapter on each side of the ESUN spool</li><li>See attached photos</li></ul>Considerations:<ul><li>Print Material: Please print with a basic PLA or PETG to minimize any shrinkage.</li><li>Too Tight? Too Loose? Cardboard expands with humidity and contracts when dried. A cardboard spool that has absorbed too much moisture may cause the adapters to fit very tight. Placing the spool in a filament dryer, such as the SUNLU S2, for a bit should resolve this. Note, you should not dry the spool with the adapters attached as they can warp in the heat. Keep in mind that after a long drying session the adapters may fit too loose. This should resolve itself shortly as the cardboard reabsorbs some moisture from the air.</li><li>AMS Lid Doesn't Close? All of the spool adapters I make are less than the official AMS spool clearance limit of 202mm, as specified on the official AMS product page, and as tested within my own AMS. However, some people have stated their spools are rubbing against the lid with the adapters attached. It's hard to say what's causing this since I cannot reproduce the issue myself, however, I've created an <a target="_blank" href="https://makerworld.com/en/models/33133" rel="nofollow noopener">AMS Lid Riser</a> which allows you to keep your AMS lid closed while providing additional clearance for larger filament spools. It's a quick and easy print which you can find on <a target="_blank" href="https://makerworld.com/en/u/243407759" rel="nofollow noopener">my profile</a> or directly here: <a target="_blank" href="https://makerworld.com/en/models/33133" rel="nofollow noopener">https://makerworld.com/en/models/33133</a></li></ul>

hmmm
