程度副詞

I don't usually like dressing in branded clothing and I don't understand why I'd pay more for something just because it has someone's logo on it.

我平常不太穿有品牌 logo 的衣服，也不懂為什麼要為了 logo 多付錢。

For the most part, there are exceptions to this rule.

I will occasionally buy some band merch as a way to more directly support music I enjoy.

我偶爾會買一些樂團周邊商品，算是直接支持我喜歡的音樂。

And I'll buy things that are functional too.

而且我也會買一些有實際功能的東西。

It's the LTT screwdriver made by the guys at Linus Tech Tips I've been eyeing these off for a little while and finally picked one up a couple of months back.

這是 Linus Tech Tips 的團隊做的 LTT screwdriver，我觀望了一陣子，終於在幾個月前入手了。

I'm happy to spend money on tools I use super regularly and a screwdriver is something I use nearly every day.

我願意花錢買我經常使用的工具，而螺絲起子幾乎每天都會用到。

So the positive reviews and practicality made the high price fairly easy to justify only with free shipping though.

所以正面的評價和實用性讓高價位變得蠻好入手的，前提是有免運啦。

Unfortunately though, 3D printing has spoiled some products for me, like this magnetic cable management system.

不過很可惜，3D列印讓我對某些產品有點挑剔了，像是這個磁吸式線材管理系統。

When I saw this I loved the idea, but when they were released I couldn't justify the price.

看到這個的時候我超喜歡這個點子，但它們剛推出的時候，我真的覺得價格太不合理了。

All I could see was something I could just print sold for many, many times the price of making it myself, and

我只覺得這是可以自己列印的東西，卻賣得比我自己做的價格高出好幾倍，

So when I started working on a bit of a behind the scenes project that would require some very particular cable management, I decided spend some of that YouTube money, thank you by the way, on the LTT Magnetic cable management gear and see if I could design something as good or better than theirs using my trusty 3D printers.

所以當我開始著手一個需要非常特別的線材管理專案時，我決定花一些 YouTube 的收入（謝謝你們啦），買 LTT 的磁吸式線材管理設備，看看能不能用我可靠的 3D 列印機設計出跟他們一樣好或更好的東西。

So the kit I went for is called the Essential Solution Kit.

所以我這次選的組合叫做 Essential Solution Kit。

In the box you get small, medium and large, what they call cable arches, a bunch of cable tie holders that pair with the included Velcro straps, a power brick mount, extra large and large arches, and

裡面有小、中、大尺寸的線材拱架，還有很多可以搭配隨附魔鬼氈束帶的線材固定座，一個電源磚固定座，特大和大的線材拱架，以及

one of the most interesting products in their range, the power bar keys.

他們產品線裡最有趣的一個產品：電源條鑰匙。

Apparently in Canada they call what we call power boards power bars.

聽說在加拿大，他們稱呼我們叫電源板的東西為電源條。

I've also heard power strips get thrown around in other parts of the world, so when you hear me say power board, just apply your local name for this.

我也聽過其他地方會用電源插座組，所以當我說電源板時，請套用你當地對應的名稱就好。

At first glance it all seems really well made and well thought out and credit where it's due.

乍看之下，這一切都做得非常精緻且考慮周到，該給的讚美還是要給。

And the packaging contained no plastic at all.

而且這個包裝完全沒有用到塑膠。

I'll go into a bit more detail on some of these later, but

之後我會更詳細地介紹其中一些，但

this is not a review or an exhaustive overview of the product.

這不是一篇評論，也不是對產品的詳盡總覽。

你可以在其他地方找到這些資訊。

Before I start ripping off another YouTuber's product like a menace, I thought I'd better use these to help understand what I'll need to replicate and maybe what I might like to improve on a little bit.

在我像個惡棍一樣開始模仿另一位 YouTuber 的產品之前，我認為我最好先用這些來瞭解我需要複製什麼，以及我可能想改進什麼。

So I decided to redo the spaghetti cables that feature under my desk.

所以我決定重新整理一下我桌子底下的義大利麵式線材。

The kit comes with metal plates for each component in the system that you can screw into non magnetic surfaces like the underside of a wooden desk.

這套組包含系統中每個元件的金屬板，你可以將它們鎖在非磁性表面上，例如木製桌子的底部。

This lets you use your magnetic arches on non ferrous surfaces.

這讓你在非鐵質表面上也能使用你的磁吸式拱架。

I use these to add attachment points for the cable arches and the cable tie holders under my desk for easy tweaking of the layout later.

我用這些來為我桌子底下的線材拱架和線材固定座增加固定點，方便之後調整佈局。

They also offer self adhesive versions of the same plates to save you having to screw them in.

他們也有提供相同金屬板的自黏版本，這樣你就不需要鎖螺絲了。

These are an additional couple of dollars each to accompany the plates.

這些是額外的幾塊錢，跟金屬板一起購買。

They offer silicone grippers for another couple of extra dollars.

他們另外再加幾塊錢提供矽膠握墊。

These are supposed to help improve grip on vertical surfaces, prevent scratching, and

這些 supposed to 幫助增加在垂直表面的抓力，防止刮傷，並且

stop the magnetic cable management parts from sliding around on a surface.

阻止磁吸式線材管理零件在表面上滑動。

These seem like a great option to have, but

這些看起來是很棒的選擇，但是

if you already have to attach something, why not just attach a regular old screw in cable tie anchor this one.

如果你已經需要固定東西了，為什麼不直接固定一個普通的螺絲固定線材固定座呢？

If you're using these on a ferrous surface like perhaps a server cabinet, you have the freedom to put your accessories wherever you'd like.

如果你們是在伺服器機櫃這種鐵質表面上使用，你們可以自由地把配件放在任何地方。

But if you want to avoid scratching, you'll need to use the silicone grips again, limiting yourself to specific locations, but

但如果你想避免刮傷，你還是需要使用矽膠握墊，這會讓你只能固定在特定位置，但是

that's something we can try and improve on.

Overall, it made managing my cables kind of fun, but

整體來說，這讓我的線材管理變得有點有趣，但是

I'm the kind of person that enjoys cable management anyway and I love how easy they will be to reuse.

我本來就是個喜歡整理線材的人，而且我很喜歡它們可以輕鬆重複使用。

The power bar holders are particularly cool and they're really strong too across the range.

電源板固定座特別酷，而且整個系列都很堅固。

Actually, the magnets are incredibly strong, which led me down a little bit of a rabbit hole.

事實上，磁力非常強，這讓我鑽研了一下。

Magnetism and the science around it really does feel like magic, and

磁力和圍繞它的科學真的感覺像魔法，而且

I'm not really qualified to teach you about it, but

my reading comprehension is pretty solid, so I'll give it a go.

我的閱讀理解能力還不錯，所以我就試試看。

Feel free to let me know what I get wrong in the comments below.

如果你們發現我哪裡說錯了，隨時在下面的留言區告訴我。

There's all kinds of complicated simulation, math and design work you can do to improve magnet performance, so when I saw these two concentric circles on the bottom of the MCM accessories, I got curious.

有很多複雜的模擬、數學和設計工作可以做來提升磁力表現，所以當我看到MCM配件底部有兩個同心圓時，我很好奇。

Now, you might be familiar with something called a pot magnet.

現在，你們可能聽過一種叫做「杯形磁鐵」的東西。

It's typically a strong neodymium magnet surrounded and backed by a sort of steel hat.

它通常是一個強力的釹磁鐵，周圍和背面有一個鋼製的「帽子」。

What that steel does is redirect the magnetic flux.

這個鋼材的作用是重新導引磁通量。

Instead of letting the magnetic fields spread out in all directions, it focuses it where the designer wants it, almost kind of like a lens.

它不會讓磁場朝四面八方擴散，而是將磁力集中在設計者想要的地方，有點像透鏡一樣。

In other words, it reduces wasted magnetic energy and pushes more of it toward the surface.

換句話說，它減少了浪費的磁能，並將更多磁力推向你想要黏附的表面。

When I saw photos of the LTT cable management stuff, I assumed that's what was going on here.

當我看到 LTT 線材管理產品的照片時，我以為這裡也是這樣做的。

But when I tore one apart, what I found was actually kind of the opposite.

但當我把它拆開時，我發現的其實是恰恰相反。

Instead of a magnet surrounded by a steel cup or hat, these are a ring magnet with a steel slug in the center.

它不是被鋼杯或鋼帽包圍的磁鐵，而是中心帶有鋼芯的環形磁鐵。

And interestingly, it seems to function in a very similar way.

有趣的是，它的功能似乎非常相似。

That steel insert appears to help shape and concentrate the magnetic field in the direction they're looking for toward the mounting surface.

這個鋼製插件似乎有助於塑造和集中磁場，使其朝向他們想要的、用於安裝的表面。

Now, I don't know exactly why they went this route.

現在，我不太確定他們為什麼會選擇這種方式。

My guess would be ease of assembly and cost.

我猜測是為了方便組裝和降低成本。

A ring magnet with a press fit steel insert is probably simpler and much cheaper than a pot magnet with those machined steel cups.

帶有壓入式鋼芯的環形磁鐵，可能比帶有精密加工鋼杯的杯形磁鐵更簡單、便宜得多。

But even with a really basic and not very scientific test, just pulling the magnet off of my pliers here, I can clearly feel the difference in strength with and without the steel slug installed.

但即使是進行一個非常基礎、不太科學的測試，只是從我的鉗子上拔下磁鐵，我都能清楚地感覺到裝有和沒有鋼芯時的磁力差異。

There's obviously been real thought put into how to maximize the power of these little magnets.

顯然，他們在如何最大化這些小磁鐵的威力上花了很多心思。

And considering the cost of high quality, high strength neodymium magnets, that's not exactly surprising.

考慮到高品質、高強度釹磁鐵的成本，這並不令人意外。

For my versions, I wouldn't have an easy way to make these steel slugs and replicate the entire design, nor the knowledge to optimize it.

對於我做的版本，我沒有簡單的方法來製作這些鋼芯並複製整個設計，也沒有知識來優化它。

But you can buy pre assembled pot magnets pretty easily.

不過，你可以很容易買到預先組好的杯形磁鐵。

The first thing I wanted to replicate was the cable arches, which seemed to be the core of the product range.

我最想複製的第一樣東西是線材拱架，這看起來是產品線的核心。

They also seemed a pretty simple starting point.

它們看起來也是一個很簡單的起點。

Obviously, my key constraint was that it should function just like the original magnetic cable management product.

很明顯，我的主要限制是它必須像原版的磁吸式線材管理產品一樣運作。

But I had some additional constraints I needed to work with.

但我還有一些額外的限制需要考量。

My design had to be easy to print, so anyone could print this at home with readily available materials and on a basic printer.

我的設計必須容易列印，這樣任何人都能在家裡用現成的材料和基本印表機列印。

And it had to be compatible with off the shelf magnets in readily available sizes.

而且它必須能搭配市面上現成尺寸的磁鐵。

They print upside down and you just install a pot magnet with a countersunk hole in the bottom with a small screw to hold it in place.

它們是倒著列印的，你只要在底部裝上一個帶有沉頭孔的杯形磁鐵，再用一顆小螺絲固定住。

The key difference between my cable arches and the LTT ones, aside from aesthetics, is these magnet covers.

我做的線材拱架和 LTT 的主要差別，除了外觀，就是這個磁鐵蓋。

The magnet covers are printed in a flexible material like TPU and and just stretch and clip over the magnets to provide a bit of extra grip and to prevent scratching.

磁鐵蓋是用像 TPU 這種彈性材料列印的，直接套上去就能固定，增加一點抓力，也能防止刮傷。

If you're not worried about scratching the surface or about your cable arch sliding off the surface, you can just use a little accent ring instead.

如果你不擔心刮傷表面，或是線材拱架從表面滑落，你也可以改用一個小小的裝飾環就好。

The model is 100% parametric, as are all the designs in this video, which means all the geometry is defined mathematically by just a handful of variables.

這個模型是 100% 參數化的，就像這支影片裡的所有設計一樣，這表示所有的幾何圖形都是由幾個變數數學定義的。

What this means for you is that you can download the model, open it in Fusion360 and and change the magnet size, width and height, and

這對你來說，就是你可以下載這個模型，在 Fusion360 裡打開，然後更改磁鐵的大小、寬度和高度，

the rest of the model will automatically adjust to suit.

然後模型的其他部分會自動調整來配合。

You can also change the size of the cable openings and Velcro strap width to adapt it to your specific use case.

你也可以改變線材開口的大小和魔鬼氈束帶的寬度，來適應你的特定使用情境。

Now, flexible filaments can be a little bit tricky to print, but

現在，彈性線材列印起來可能會有點小技巧，但是

thanks to today's sponsor, Prusa Research, it's easier than ever.

多虧了今天的贊助商 Prusa Research，這變得比以往任何時候都更容易。

One of my favorite things about Prusa printers is the fact that Prusa continually improves on their designs and often provides everything you need to upgrade your printer to the latest spec as new iterations are released.

我最喜歡 Prusa 印表機的一點就是，Prusa 會不斷改進他們的設計，而且當新版本推出時，通常會提供你所有需要的東西來升級你的印表機到最新規格。

Alongside the Core One L, they released the updated Core One plus that adds a lot of those quality of life features from their new printer to the core one.

另外，他們也推出了更新版的 Core One plus，加入了許多他們新印表機的實用功能到 Core One 上。

And they released a kit to take your core one to plus spec for less than 20 bucks.

而且他們推出了一個套件，讓你用不到 20 美元就能把你的 Core One 升級到 plus 版本。

You could even print the parts yourself and have your printer build your upgrade kit for itself for free.

你甚至可以自己列印零件，讓你的印表機免費打造自己的升級套件。

One of the best new additions in the plus spec is the updated filament sensor, which makes it way easier to use flexible filaments in your Core one.

plus 版本其中一個最棒的新增功能就是更新的線材感測器，這讓在 Core One 上使用彈性線材變得容易多了。

Because flexible filaments are flexible, it's difficult to push them through the filament feed tube and past the filament sensors.

因為彈性線材很軟，要把它們穿過線材饋管並通過線材感測器會比較困難。

Prusa recognized this shortcoming in the Core One and designed a new version of the sensor that includes a switch to make it easier to get the filament through the tube and to the print head.

Prusa 注意到 Core One 的這個缺點，並設計了一個新版本的感測器，裡面有一個開關，讓線材更容易穿過管子並到達列印頭。

So with this upgrade installed on my printer, loading and printing TPU for the magnet covers was dead simple.

所以，在我這臺印表機上安裝了這個升級後，載入並列印 TPU 來製作磁吸蓋板變得非常簡單。

This kind of thing is what makes Prusa unique among a sea of printer manufacturers these days.

這種做法讓 Prusa 在現今眾多印表機製造商中顯得獨樹一格。

Not only are they iterating on their designs to sell you new and improved printers, but

他們不僅會改進設計來賣給你新且更好的印表機，

they're also making sure your old Prusa isn't left behind behind every time a new feature is released.

而且還確保了你的舊款 Prusa 在每次推出新功能時都不會被拋在後面。
