RedditのR/GuitarとR/3Dprintingに同時期に上がった投稿が話題になっています。ヴィンテージのストラトキャスター(Fender製)の製造中止部品を、3Dプリンターで自作して復活させたというレポートです。
何が困っていたのか
問題になっていたのは2点。トレモロアームのつまみと、ストラップロックアダプターです。どちらも製造が終了していて、eBayで探すと1個200ドル(約3万円)以上する状態でした。
Let's be real, there are still people out there wondering, "What exactly do you even use a 3D printer for?" Honestly, in the early days, even I just thought, "Oh, you can make toys with it, right?" (laughs). But what I stumbled upon on Reddit recently? That was truly one of those moments where I slapped my knee and went, "Aha! This! This is the true power of 3D printing!"
Vintage Parts, Modern Solutions
There's a post that went viral on both r/Guitar, a forum for guitar enthusiasts, and r/3Dprinting, for 3D printer lovers. Apparently, a guitarist was having trouble finding parts for a vintage Stratocaster: specifically, a tremolo arm tip and a strap lock adapter. These are long-discontinued items that can fetch over $200 (about 30,000 yen) on eBay.
[kira]Wow, this is truly impressive! [smile]I totally get that feeling of 'Aha! This is what 3D printers are for!' [kira]It's amazing how a simple, affordable solution can tackle such an expensive and frustrating problem.[normal]
どうやって作ったか
元の部品をノギスで計測して、寸法を記録。3DソフトのBlenderでモデリングして、Bambu Lab A1 Miniで印刷しました。素材はシルクPLA(光沢感のある仕上がりになる素材)です。
特に難しかったのはトレモロアームのつまみで、ネジ山がM6×1.0という規格を正確に再現しないと本体に固定できません。試作を4回繰り返してようやく合格レベルになったとのことです。
コストはたったの1.2ドル
2点合わせて使ったフィラメントは約30g。フィラメントのコストに換算すると約1.2ドル(180円程度)です。200ドル超えの代替品として、180円で対応できたことになります。
完成品の写真を見ると、元のパーツと区別がつかないレベルの仕上がりで、Redditのコメント欄では「これこそ3Dプリンターの存在意義」という声が相次ぎました。
大切な楽器を守れる技術として
廃盤になった部品、入手困難な補修パーツ、製造元が倒産してしまったアイテム。こういった問題を「自分で作る」という選択肢で解決できるのが3Dプリンターの真骨頂です。ギタリストに限らず、修理したいけど部品が手に入らなくて困っている方には、ぜひ参考にしてほしい事例です。
So, what did he do? He DIY'd them with a 3D printer! He measured the original parts with calipers and modeled them using Blender, a 3D software. He used a Bambu Lab A1 Mini printer and silk PLA filament. Honestly, this Bambu Lab printer has a reputation for being pretty good among recent compact models. I bet the printing process was super smooth.
For the tremolo arm tip, the M6x1.0 screw thread was crucial, so he reportedly went through four prototypes. All that effort paid off! The total filament used for all parts was a mere 30g, which translates to about $1.20 – less than 200 yen. Considering the original parts were over $200, this is just incredible. Check out the original post for more details!
"This is the Real Value of 3D Printing"
Looking at the photos of the finished parts, they're practically indistinguishable from the originals. The comments section exploded with remarks like, "This is exactly why 3D printers exist!" And I totally agree. Instead of throwing something away because it's broken, or giving up because it's too expensive, having the option to "fix it yourself" or "make it yourself" is truly amazing.
Ultimately, the benefit for us users is solving problems like "I can't get what I want" or "It's too expensive." This guitarist's example is a perfect illustration. Whether it's for hobbies or work, I bet there are surprisingly many people struggling to find discontinued parts. In those moments, I hope they remember, "Oh, right. There's always 3D printing!"
