MOD for using "Stronger Compact Spool Auto-Rewinder by rans" on SUNLU S1

Description

[English]

I've tried various buffers and auto rewinders for MMU2S, and I finally found something satisfactory. That name is “Stronger Compact Spool Auto-Rewinder by rans”.

It is great that it rewinds moderately, even if there is a lot of filament left or when there is little filament left. The badge-reel spring is much more powerful and more durable than the printed spring.  It is wonderful that compact with a width of 100mm including the holder. And the parts are also compact, so it's great to be able to print in a short time with a few filaments!

I came up with an idea, wouldn't this fit into my favorite filament dryer SUNLU S1? I tried and it worked well, so I will release this as a remix. It is useful with single-colored 3D printers as well as MMUs. Sometimes, the reel in the S1 pulled and not rotate well when there is little filament left, but you will be able to run smoothly until the end with this spool.

For convenience, the STLs of the parts that have not been modified from the remix source has also been uploaded with the creater name.

Please print the parts used with the SUNLU S1 with heat-resistant filament (PETG/ABS/ASA).

4 bearings(608Z) and 1 spring removed from The badge-reel are required for each spool.

(Nov.7 2024 Updated)

The size of base.stl has been slightly modified. I made it 1mm higher because it came into contact with the S1 roller with a larger reel. In addition, the width was also increased by 1mm and made it just the right size with S1.

(Nov.9 2024 Updated)

I forgot to publish bearing_holder.stl, so I added it. I'm sorry for those who couldn't assemble this model.

Thank you for creating a wonderful work!

MMU2Sのために様々なバッファーや自動リワインドスプールを試してきましたが、ついに満足できるものを見つけました。Oleksii Morozさんの「Compact Spool Auto-Rewinder」をransさんが改良した「Stronger Compact Spool Auto-Rewinder」です。フィラメントがたくさん残っている状態でも、残り少ない状態でも、適度に巻き戻してくれるのが素晴らしい。安価なキーリールを分解して中の金属製のバネを流用するので、3Dプリントしたバネよりもはるかに強力で耐久性がありますし、専用のホルダーに入れても幅100mmとコンパクトなので、たくさん並べても場所を取りません。部品もコンパクトなので少ないフィラメントで短時間にプリントできるのも最高!

このコンパクトさなら、私が愛用しているフィラメントドライヤーSUNLU S1にも入ってしまうのでは?と閃き、専用の土台と軸受を作ったところうまくいったので、Remixとして公開します。多色用の3Dプリンターで使うのはもちろんですが、普通の単色3DプリンターでSUNLU S1を使っている人にもおすすめです。フィラメントが残り少なくなったときに、S1の中のリールがうまく回転しないで引っ張られてしまうことはありませんか?このスプールを使えば最後までスムーズに回るようになります。

利便性のため、Remix元から改変していないパーツも制作者名を明記の上STLをアップしました。

SUNLU S1と一緒に使うパーツは熱に強いフィラメント(PETG/ABS/ASA)でプリントしてください。スプール1つにつき608Zベアリング4つとキーリールから取り出したバネが1つ必要です。私はSeriaで購入した65cmまで伸びるタイプを使いました。

(2024.11.7 追記)

base.stlのサイズを若干修正しました。大きめのリールでS1のローラーに接触することがあったので1mm高くしました。また横幅も1mm大きくしてジャストサイズにしました。

(2024.11.9 追記)

bearing_holder.stlの公開を忘れていたので追加しました。うまく組み立てができなかった方、申し訳ありませんでした。
