Für unsere Müllcontainerbox habe ich in #CAD ein Ersatzteil für den Verschluss erstellt (ich bin noch am Lernen) und es aus PETG gedruckt (mal gucken wie lange es hält sonst versuche ich es mit ASA).

So klappt der Deckel nicht mehr bei jedem großen Windstoß (davon gibt es hier reichlich) auf 😊 #3Dprinting

🌘 實際繪製非橢圓的卵形
➤ 從CAD橢圓到實用圓弧的轉換技巧
medium.com/@brunopostle/actual
本文介紹一種將CAD繪製的橢圓轉換為由固定半徑圓弧組成的曲線的技術,以便於實際建築應用。作者分享了他利用圓形分割和角度控制的方法,將橢圓分解為多個圓弧段,並展示了使用不同角度分割(例如45度、30度、15度、10度)的案例,以及三中心拱的應用。這種方法不僅能近似橢圓形狀,還能讓建築結構的各部分角度保持整齊,方便施工。
+ 這篇文章解釋得非常清楚,讓我瞭解瞭如何將理論上的設計應用到實際的建築建造中。
+ 以前總覺得橢圓形的結構很難實現,現在有了這種方法,感覺可行性大大提高了!

Medium · Actually drawing some ovals (that are not ellipses)By Bruno Postle

anyone know of a 3d print model for something designed to attach to a roll of flat material (like, paper/film/etc) for cutting it into rectangles? like, something with a straight guide and a little attached razor blade and such

Finally was in the mood for some PCB work. I'd be lying if I'd say that I don't feel a little bit smug about this v3 mobo

Because it's tiny and fully reversible. I'm particularly smug about that reversible nice!view display connector. Oh, and it scales to 4x6 matrix for larger builds too!

Re: #3dprinting & #3dDesign

I've become ... 'better ' at it, but one of the core things I'm missing is how folks do design when it needs to work with other complex parts.
For example; My #3dprinter is basically a custom component at this point. I had to design the sled to use with the rails, every component outside of the bed-base and the extrusion frame is custom or customized.

I'm looking at making a big upgrade to the hot end but nobody makes my part, and I need a cooling solution. So how do I design a fan/duct system that mounts to my hot end mount, fits all the pieces and is the right length?

It seems incredibly daunting to have to #CAD up the entire assembly from scratch. But other folks do this... Somehow? If I look for cooling solutions on any print-sharing website there are thousands of them.

What am I missing here? 🙁
