<h3>WDT is an art. Its chaotic nature takes skill to master consistently.</h3><h4>Umikot is a Tagalog word which means: to spin; to turn around; to revolve; to rotate; to circle; to go around; to swirl; to gyrate.</h4>In that spirit, this 3D printable tool utilizes a print-in-place planetary gear mechanism to create spirographic needle motion. This is the 58mm version. Looking for the 54mm version? <a target="_blank" href="https://makerworld.com/en/models/169733" rel="nofollow noopener">See here.</a> <a target="_blank" href="https://paypal.me/vjapolitzer" rel="nofollow noopener">Like what I'm doing and want to share the love?

The spirographic pattern avoids needles crossing the same path, with the goal of a more homogeneous particle distribution.I have optimized the needle pattern for even coverage, and no more than 8 rotations of the handle should be necessary. Two different needle lengths provide deep and top of the bed distribution.<figure class="image image-style-align-center"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_ray4uaae3dcj.jpg"></figure>The needles are inserted from the top and are replaceable, and the base is swappable, allowing for configurable needle depth for different baskets, without needing to change out the needles. Optionally, you can print versions of the base that can house eight magnets and/or include a flange to interface with the portafilter lugs. A little de-bossed label to indicate a given base's depth is included for easier identification.<h3>Instructions</h3><h4>Gather your parts and materials.</h4><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_qs894dwer08d.jpeg"></figure>For the non-printed things, you will need:<ul><li>5x M3 x 12mm flathead/countersunk screws (if you have non-flathead/countersunk screws you would like to use, try the noCountersunk files)</li><li>10x 0.35mm acupuncture needles with a 30mm handle (Compatible with the same as the popular 9-prong tool, 0.35x75mm from <a target="_blank" href="https://www.aliexpress.com/item/1005001467649993.html" rel="nofollow noopener">aliexpress</a>)<ul><li>OR! 10x acupuncture needles with a 20mm handle for the 58s (short) upper. 30mm handled needles can work with the 58s upper, but the handles will reach the basket lip with the 25mm depth base.</li></ul></li><li>[OPTIONAL] 8x 5x3mm magnets for the each base you wish to print</li><li>Cheap flush-cutters you don't mind dedicating to needle cutting, or even better, a hardened cable cutter</li><li>Screw-driver/Allen-key for the M3 screws</li><li>A 3D printer</li></ul><h4>Print your parts!</h4>I printed mine with PLA. You may want to print the Base part with PETG.Personally, the contact time with the hot basket/portafilter has been short enough that I have not had issues with PLA - however, PETG, with its higher glass transition temperature, would certainly have reduced risk of softening.Settings:<ul><li>0.2mm layers</li><li>4 top/bottom layers</li><li>2 walls are sufficient</li><li>11% gyroid minimum (consider higher for more heft!)</li><li>No supports</li><li>Concentric top pattern for Spin Ring V2</li><li>Concentric bottom pattern for Mech V2</li><li>Random z-seam for Upper Mech can help with snagging and improve smoothness [Thanks to zumicroom in EAF]</li></ul>The gears and needle holes require a good calibration (0.2mm XY print-in-place tolerance) and good quality filament!Printed Parts:<ul><li>1x Mech (choose the short version for needles with 20mm handles)</li><li>1x Spin Ring</li><li>1x Handle (see Handle Options below)</li><li>1x Base (see Base Options below)</li><li>1x Stand (see Stand Options below)</li></ul>Handle OptionsThe Handle is available in Small and Large. Which to use comes down to preference.The pictured Umikot is fitted with a Small, which is good for small hands or those that want a delicate-operation feel (that is my personal preference, but go with what feels good for you!)Base OptionsThe Base part is available in different versions for:<ul><li>Various needle depths</li><li>With or without a flange that interfaces with the portafilter lugs/ears (LongTab/ShortTab/NoTab)<ul><li>The Long Tab version protects the needles, but is not compatible with many tamping stands.</li><li>The Short Tab version provides the stability of the tabs, but loses the protection of the needles in favor of more tamping stand compatibility</li><li>The No Tab version should be compatible with any tamping stand, and is available with holes for 5x3mm magnets (5x3Mag)</li></ul></li></ul>Pick the needle depth that fits your 58mm basket. The filenames include the depth (i.e. Umikot58 - Base V2 25mm LongTab.stl). This is how deep the needles extend below the lip of the basket. See below for some common needle depths.My favorite is the LongTab base.Note that the default Lug files support PF lugs/ears <27mm wide. For a more tailored fit, or for wider lugs/ears like on some La Marzocco portafilters, check out the OnShape link to generate different widths.I prefer versions without magnets, as it is easier to gently lift Umikot after distribution without disturbing the grounds. You may like the feeling of the magnets and the easier one-handed use they provide - pick what you like!Common 58mm basket needle depths are:<ul><li>15g basket<ul><li>21mm</li></ul></li><li>18g basket<ul><li>23mm</li></ul></li><li>20g basket<ul><li>25mm</li></ul></li><li>22g basket<ul><li>27mm</li></ul></li><li>25g basket<ul><li>30mm</li></ul></li><li>Sworks 18-20g basket<ul><li>23mm</li></ul></li><li>Weber Workshops 18-22g basket (old version)<ul><li>24mm</li></ul></li><li>Pullman 19-20g basket, Weber Workshops 20g basket<ul><li>25mm</li></ul></li></ul>Note: For the very best fit, measure the internal depth of your basket. The above are based on specifications and have not all been tested. Please let me know if these recommendations need adjustments!Stand OptionsPrint the corresponding stand, LongTab, ShortTab, or NoTab, depending on the base you choose.<h4>Cut the needles to size.</h4>The designed needle depth for the various base files assumes the needle length to be cut precisely. If anything, favor slightly short. You only need to cut to the lengths described below. The base you choose is what adjusts the effective needle depth.The needles are likely harder than the cutting edges of most cheap flush cutters, so be prepared to dedicate them to the cause. I used a very inexpensive one from a multi-pack I got off of Amazon. Even better, use a proper, hardened cable cutter.Be very careful to safely dispose of the cut ends of these needles!First, cut 5 of your 10 needles to a total length of 65mm (35mm needle + 30mm handle):<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_ju27nji1fm2a.jpg"></figure>Cut the remaining 5 needles to a total length of 55mm (25mm needle + 30mm handle):<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_q5tv7k8tgprv.jpg"></figure>NOTE! For the Umikot58s SHORT version of the mechanism, cut all your 20mm handled needles 10mm shorter (55mm and 45mm).<h4>Give the needle handles a slight bend</h4><figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_z3srpu33b7tn.jpg"></figure>To secure the needles in their places in the gears, give them a little bend, like in the above photo. This way they won't rattle around, but can still be removed if they ever need to be replaced.<h4>[Optional] “Tap” the gears' screw-holes</h4>This step is optional, particularly if your screw holes are quite tight. To make our lives a bit easier later, “tap” the holes with one of your M3 screws. Carefully screw them into each of the gears' holes, stopping when you feel the resistance noticeably increase (you've hit the bottom) and then remove the screw. Repeat for each of the 4 larger gears. You will need to hold the gears carefully to keep them from rotating while you do this. Be careful you do not get pinched!<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_cpcbcra9tqh4.jpg"></figure><h4>[Optional] Lubricate the Spin Ring</h4>For the smoothest operation, the V2 mechanism can benefit from some lubrication. I recommend rubbing some paraffin wax (such as from a tealight candle) on the inner surfaces of the Spin Ring.<figure class="image image_resized image-style-align-center" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_ny5x8vldpfs4.png"></figure><h4>Attach the spin ring and handle</h4>Gently screw in 4 of the M3 screws to attach the spin ring. Fully tighten until they stop (the mechanism should be locked). Then back out 1 turn, which will align the gears vertically to the outer ring gear.<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_d78ytpulg4w7.jpg"></figure>Then, do the same for the handle, but only back out ~¼ turn:<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_048qzrr41byh.jpg"></figure><h4>Insert the needles!</h4>Be careful during this step - the trimmed needles are still thin and sharp! Gently insert each needle fully into the gears from the bottom. Do not force them! The slight bend in the handle will secure them. If a needle is too loose, make the bend a touch more.<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_toy5c8wid5bi.jpg"></figure>(58mm Short version pictured)See below for the needle pattern with respect to the different needle lengths:<figure class="image image_resized" style="width:75%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_tk7vpzmg4n6c.jpg"></figure><h4>Attach your base</h4>[Optionally, press in the magnets if you went with the 5x3Mag version.] Screw on your chosen base. You can change bases at any time, but be very careful when doing so, as the needles are pokey!<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_zmnc06swdtlh.jpg"></figure>(58mm Short version pictured)<h4>Distribute some coffee!</h4>And that is it! If you chose the NoMagnet NoLug base or the Magnet NoLug base but your basket isn't very magnetic, you will need to hold Umikot down while turning the mechanism. Gently give it several rotations. At least 8 gives the pattern nearly full coverage, but I like to do as many as 12 - whatever gives you the best results!The distribution must be done with the basket in a level position - otherwise, the grounds will tend towards whichever direction the basket is tilted.Finally, remove Umikot, give the portafilter a tap to settle the grounds, tamp, pull, and enjoy your espresso!<figure class="image image_resized" style="width:50%;"><img src="https://makerworld.bblmw.com/makerworld/draft/643836/2024-02-04_25a4ng5b0e66.jpg"></figure>Disclaimer: not all filaments, nor the 3D-printing process, are certified food safe.

<h2>Summary</h2>The diameters available are: 12.5mm 1/2&#34; approx (4.5 mm countersunk screw hole) 15mm 19/32&#34; approx (4.5 mm countersunk screw hole) 22mm 7/8&#34; approx (4.5 mm countersunk screw hole) 25mm (4.5 mm countersunk screw hole) 25.4mm 1&#34; (4.5 mm countersunk screw hole) 30mm 1 3/16&#34; approx (4.5 mm countersunk screw hole) 32mm 1 17/64&#34; approx (5 mm countersunk screw hole) 35mm 1 3/8&#34; approx (5 mm countersunk screw hole) 40mm 1 37/64&#34; approx (5 mm countersunk screw hole) 50mm 1 31/32&#34; approx (5 mm countersunk screw hole) 62.5mm 2 29/64&#34; approx (5 mm countersunk screw hole)My thinking with these clips is that they are ideal if you&#39;ve got a small job where you need to secure some pipes. They&#39;re never going to replace the economy of buying a trade pack of regular clips for a big job, but hopefully some of you will find them useful and also make use of the fact that they can be easily unclipped if required.It would be great to see your makes and get some feedback on how you have used them.                                       Notes:                    Print with the front flat surface down.

Update:18th of Jun 2024<ol><li>Just tidying up of the files and a small update for the nozzles. </li><li>The Paint-On numbered covers are kept as a seperate file</li><li>The extra nozzles are now part of the main file.</li></ol>&nbsp;12th of Jun 2024<ol><li>Tweaked the port holes so it grips the PTFE tubes better. (In case you don&#39;t know, you can use PTFE tubes instead of the printed nozzles)</li><li>Very slightly narrow the for hole for the hygrometer so it fits tighter.</li><li>Changed the style of the brackets and the fonts to match that of the Covers</li></ol>11th of Jun 2024<ol><li>Tweaked the internal geometry of the nozzles to reduce rubbing as the filament travels through it. </li><li>If you feel are you getting too much resistance or rubbing from the original Nozzles, you can try wider Nozzles. You can find the Nozzle Pack under print profiles. These nozzles comes in a choice of Original, +0.05 and +0.10. </li></ol>8th of Jun 2024<ol><li>Sliced abit off the side of the cover to make the cover easier to fit when using the top mount. I missed the measurement, it will fit, but just barely. If you are using my Clip-On Top Mount, I&#39;ve updated the file so it works now. </li><li>I&#39;ve brought back the Paint-On numbers for the cover. You can color it yourself (the stencil will appear when you use the Bambu Studio Paint function) or you can just use the one I uploaded under print profiles. <img class="image_resized" style="width: 45.16%" src="https://makerworld.bblmw.com/makerworld/model/DSM00000000486153/design/2024-06-09_cc8d5d3eff2808.jpg"></li><li>Small adjustments to the clips to make it snap tighter. I&#39;ve also reduced the size of the release lever incase it catches on the spool.</li></ol>&nbsp;&nbsp;Finally I&#39;ve created the ULTIMATE FILAMENT SPOOL ENCLOSURE for the AMS LITE!&nbsp;Thank you for all the support and feedback on the previous design. I’ve incorporated everything I’ve learned to create a new design that I believe is better and more user-friendly. Now, installing and feeding filament is so much easier. The cover is attached using clips, making the process more straightforward. No additional tools or parts are needed, and you have a choice of action panels and action buckets to suit your needs.&nbsp;My favorite action panel is the dual monitoring (inside/outside) hygrometer panel.&nbsp;This is also compatible with my and Bambulab&#39;s AMS lite top mount. You&#39;ll need to remove the screw on the Bambulab version.&nbsp;Installation is also relatively easy. Let’s get started!&nbsp;NOTE PLA for all partsPETG for the clips&nbsp;InstructionsConnect the buckets together as shown using the clips.<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000486153/design/2024-06-06_c0d1267bb22298.jpg"></figure>Install the plugs by press-fitting them. They don&#39;t need to go in all the way; stop once they are tight. The round-based ones are for the filament to go through, while the square ones are for sealing. &nbsp;I&#39;ve also designed it so that you can use a PTFE tube if preferred. Just gently push it through the hole. I would recommend a very short tube of 2 to 4cm.<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/model/DSM00000000486153/design/2024-06-06_d54667eaaf1b5.jpg"></figure>Install the setup onto the AMS Lite.

It sits flush when installed correctly.
