经过N次失败，终于改出了一版比较满意的方案建议内部不加支撑。参考图片方案加支撑打印让然，各位大哥有更好的建议，也可以提供一下，我实在整不明白支撑。

<h3>If you want commercial license, check out my bio and get it from Patreon.</h3>&nbsp;<h3>I am here to introduce you, retractable dragon wand! I made this design for Makerworld dragon contest (3/5). I think it will be a great addition Ornaments and toy for kids for new Dragon year. </h3>&nbsp;<h3>Best wishes to you all! 新年快乐.</h3>&nbsp;This wand takes me a while to design and tests. It takes around 2h33m to print and cost right around 50g filaments.The retractable part is not super rigid, it's by design, I did not put a lot of parameter in there, consider this will most gives to kids to play. So rather it break than hurt somebody.&nbsp;<h2>Update:</h2><h3>v1.5 (1/13/24) - Fix internal parts geometeric issue. (tested) It only applys on P & X Series profile.</h3>Printing profile for P & X Series have found geometric issues on inner parts. Which only occurs when selecting P&X series printers, A1 and A1mini profile doesn't have this issue. Internal parts have been redo. Profile for a1 mini, A1 have remained as v1.4 since it is working correctly.&nbsp;&nbsp;<h2>Detail display:</h2><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/413415/2024-01-11_161fe41bfd6c.gif"></figure>&nbsp;&nbsp;<h3>My other wand design: </h3>Loong Wand:<a target="_blank" href="https://makerworld.com/en/models/143028#profileId-155486" rel="nofollow noopener">https://makerworld.com/en/models/143028#profileId-155486</a><figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/413415/2024-01-16_55943d4f3e579.jpg"></figure>&nbsp;Harry Potter Wand: <a target="_blank" href="https://makerworld.com/en/models/68778#profileId-72937" rel="nofollow noopener">https://makerworld.com/en/models/68778#profileId-72937</a> <figure class="image image_resized" style="width:69.8%;"><img src="https://makerworld.bblmw.com/makerworld/draft/413415/2024-01-11_db6b2ce5b060b.jpg"></figure>&nbsp;<h2>Instruction:</h2>I put very large size of brim on all my printing profile, with 0mm gap to ensure the printing success rate. Since this model is a bit challenge to print.You will required to do some post work of removing brim off. It should be very simple. I have increased gap on first layer from design, so it is tight tolerance, but not super tight.&nbsp;&nbsp;<h2>Materials:</h2>If you are printing with some high shrinkage rate filaments, like some of the silk filament. Due to the sinkage rate different. Your part might slide out or break very easily. So, use some good filaments.&nbsp;<h2>Design:</h2>Let's talk about a little bit of design. The retractable mechanism is very simple, the inner piece is interlocking with outter pieces.<figure class="image image_resized" style="width:24.07%;"><img src="https://makerworld.bblmw.com/makerworld/draft/413415/2024-01-11_651c54592313e.png"></figure>Style is more challenging<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/413415/2024-01-11_37b064643dfb6.png"></figure>Adding more details.<figure class="image"><img src="https://makerworld.bblmw.com/makerworld/draft/413415/2024-01-11_d16c3620c7aab.png"></figure><h2>Printing suggestions:</h2>This is a tall object with very small contact area on first layer. It is challenge to print. It will print without brims, but it fail very easily that way. If you are slicing the model yourself, make sure you add brims, and set brim gap to 0mm. Also increase the first layer thickness.Or, just use those profile that I put there. It all have been tested and confirm works.&nbsp;&nbsp;&nbsp;

Dragon Wand (Retractable) v1.5

Here's improved flow calibration compared to Orca or Bambu Studio. This is the third iteration from the original models: <a target="_blank" href="https://makerworld.com/en/models/108065#profileId-115396" rel="nofollow noopener">Improved flow ratio (extrusion multiplier) calibration v1 by jimcorner - MakerWorld</a>, <a target="_blank" href="https://makerworld.com/en/models/179247" rel="nofollow noopener">Improved Flow Calibration v2 by jimcorner - MakerWorld</a>. The goal is to make flow rate calibration as straightforward as possible with a repeatable and clear standard.&nbsp;Please download the 3mf file and slice it yourself in Orca, the 3mf does not work with Bambu Studio bc it doesn't support per object flow ratio setting! As a result, the print profiles uploaded by other people here likely won't work.&nbsp;Why I upload this:<ol><li>the default flow calibration is bad at determining which flow rate has the smoothest surface with the monotonic top infill pattern, especially for white filaments. The result is often subjective.</li><li>There are too many test pieces to keep track of.</li></ol>What's improved compared with Orca/Bambu Studio:<ol><li>The result is now much more definitive and clear, I can even capture it with my phone camera as shown in the photos</li><li>The top surface is Archimedean Chords pattern instead of monotonic, and line width is increased to 0.6mm, making it much easier to tell which flow rate is the best and take out the guess work. All other settings are exactly the same as Orca Slicer/Bambu Studio flow ratio calibration, so the calibration print is set up similar to originally intended.</li><li>The test pieces are put together as one piece, instead of 10 smaller pieces that tends to clutter up space and easy to be lost.</li></ol>How to use this test:Prerequisite: open the 3mf file in orca slicer, and select the filament you want to calibrate.<ol><li>Pass 1: change the flow ratio in the filament tab to 1.0. Once that's set correctly, the flow ratio of the 7 pieces are: 1.12, 1.08, 1.04, 1, 0.96, 0.92, 0.88. Slice plate 1 named “rough”, and print. Find the flow ratio right before the raised right half circle appears, as flow_rate_rough. Usually this number is around 1.0, and if you know the ballpark number, you can use that value and skip this step.</li><li>Pass 2: change the flow ratio in the filament tab to flow_rate_rough from pass 1. Slice and print the second plate named “fine”. Going from bottom to top, find the second flow ratio that gives the raised right half circle, as captured in the photos above. This is the optimal value to use for future printing.</li><li>Optional: If there are fewer than two pieces with the raised right half circle, repeat pass 2 with increased value for flow_rate_rough.</li></ol>&nbsp;Notes: in pass 2, the flow ratio of the 7 pieces are: [1.03*flow_rate_rough, 1.02*flow_rate_rough, 1.01*flow_rate_rough, 1*flow_rate_rough, 0.99*flow_rate_rough, 0.98*flow_rate_rough, 0.97*flow_rate_rough]. You can also see this in the per object setting → quality → flow ratio. The actual flow ratio when printing is the filament flow ratio value set in the filament tab * the scalar set in the per object flow ratio scalar.&nbsp;&nbsp;Why/how well this works:The optimal flow ratio should make the lines squish into each other to fill the gaps, but they should not be squished together too much because severe over extrusion creates ridges and uneven surfaces. The goal is to find the optimal flow ratio for the right amount of squishiness between the extrusion lines. Here the Archimedean Chords pattern and larger line width of 0.6 amplify the effect of between-line-squishiness by inspecting the raised right half circle. As the flow rate goes up from the bottom to the top of the test pieces, the optimal flow rate would be somewhere when the raised right half circles start to appear as it means the lines start to get squished together. To account for the test error bar and filament diameter variation, I choose the second visible raised right half circle for the optimal flow ratio. In my testing this gives a smooth top surface in my normal prints with minimal/no signs of over-extrusion. And the results I get is consistent with the values provided by the manufacturers as well, which gives me confidence as this method converges with manufacturers suggestions. For example, in the photos, the red filament is polylite pla which has 0.95 flow ratio recommended by polymaker, and my test gives 0.95. The white filament is sunlu pla+ has recommended 0.98 flow ratio and my test gives 0.98.&nbsp;
