总的来说，体验非常棒。👏 网页的定制没问题，可以下载到stl文件。我打算把获取的文件去白嫖一波嘉立创的3D打印，但是上传以后提示有坏边和反向三角面。（白嫖失败）可能生成的stl文件不够严格？

@"xyzyx"#p84720 请问是哪个文件有坏边和反向三角面？是这个挂件还是桌面呼号牌？桌面呼号牌可以减小弧形分段数量解决这个问题，挂件还没有这个功能，如果是挂件出现坏边和反向三角面我就加一下。感谢您的测试！

@"BI3TJT"#p84740 沉金好看的！可惜每月的券都拿去打别的板子了哈哈，3d打印方便一点😆

@"BI3TJT"#p84740 这个不错哎可以发一个么

@"BI9CBD"#p84723 挂件这个会提示，桌牌我还没试。

@"xyzyx"#p84764 请调整一下 fnnum 为32或者16试一下，以及使用修复工具

在桌面多彩呼号牌模型在线自制器发布之后，终于购入了3D打印机，能够便捷的尝试打印业余无线电相关的小物件。实际入手后发现之前的多彩模型使用FDM打印较为繁琐，后续要重新进行设计，在此之前制作了呼号牌挂件（钥匙扣）在线自制器。使用JLC的打印券可以一并打印。

和之前一样，是使用Maker World的在线编辑器进行制作，🔗可定制挂件/钥匙扣。定制中的Callsign_logo是带有CRAC Logo的版本，需要手动上传svg文件。mini版本为小尺寸的纯文字版本，具体效果见下文。

CRAC的logo需要在svg file处上传，上传成功会显示图片，无法上传请刷新或上传后耐心等待。文件请前往Gitee进行下载

编辑正面文字即可改变呼号，同时可编辑第二行的文字

如果默认整体尺寸不合适可在下图对应修改

mini版本默认开启背面文字，修改位置如下

mini版本正面因为我使用的是0.4mm的喷嘴，选Noto Serif字体时打印精度不够，因此更换了字体。您也可以自行修改所有的字体，都有预留接口，具体操作可参考之前定制桌面呼号牌的帖子。

打印出来效果如下：

为了直观展示尺寸，与PL330进行对比

Overall, the experience was excellent.👏
Customization of the webpage is fine; it's possible to download the STL file.
I intended to use the downloaded files to get a free trial of Formlabs' 3D printing service, but after uploading, I received an error message indicating that there were invalid edges and inverted triangles. (Trial failed)
The generated STL file might not be strict enough?

BI9CBD

xyzyx Which file has the bad edge and inverted triangle face? Is it this pendant or the desktop callplate? The desktop callplate can reduce the number of curved segments to solve this problem. The pendant does not have this function, so if the pendant has a bad edge and an inverted triangle face, I will add one. Thank you for your testing!

xyzyx

BI9CBD The notification indicates that I haven't tried the nameplate yet.

BI9CBD

I tested it, and when the logo is included, it shows a bad edge. I'm not sure where the problem is occurring. Could someone from another team please help me understand?

The number of arc segments for the desktop callplate can be adjusted as shown in the image, reducing it to 32 or less to attempt repairing the inverted triangular face.

BI9CBD

I released all the parameters for the circular arc segment and tested it, but the results were not significant.

You can use an online repair tool to fix the damaged edge. After testing, I found that JLC is now printable after the repair.

As for the keychains, the JLCPCB I used also produced good results. This is one that I designed myself using EDA software, and the results are quite good. The resolution of the pattern is slightly better than that achieved with 3D printing.

BI9CBD

BI3TJT The gold-plated ones look great! However, I've been using all my monthly coupons to buy other stocks, haha. 3D printing is more convenient.😆

BG2EFX

BI3TJT This looks good! Could you send me one?

BI3TJT

BG2EFX You can check out the Jiali Create open-source hardware platform, which has many good keychain designs, and also involves things like changing call signs. You might need to do some of this yourself.

BI9CBD

xyzyx Please try setting `fnnum` to either 32 or 16, and also use the repair tool.

BI9CBD
No problem at all, the repair tools provided by JiaLiChuang can handle it. Once I'm done with them, I can place an order for samples. I have already placed one, so we'll see how it goes. Hehe.😜

BI9CBD

I've made a simple update, now you can create plaques with a slot wall thickness and key ring height of 0. It uses 3m double-sided adhesive tape for a secure attachment.

It's a really fun little thing, thanks for sharing this with us!
