Welcome to the tutorial on how to upgrade your single material Original Prusa i3 MK3S/MK3/MK2.5S/MK2.5 to Original Prusa i3 MK3S/MK2.5S MMU2S
Directly compatible printers:
Original Prusa i3 MK3S and MK3
Incompatible printers:
Original Prusa MK3 or MK2.5, older MMU2S packages included extruder upgrade, if yours does not, please upgrade first to MK3S+ extruder.
Original Prusa i3 MK2/S (please upgrade first to MK2.5S)
Original Prusa i3 MK2/S MMU1 (please use a different package MMU1 to MMU2S)
For those upgrading MMU2 to MMU2S, please follow chapters 2 and 3 to rebuild the extruder, then skip to chapter 6 (around step 22), assemble buffer in 7 and calibrate printer according to chapter 8.
The kit includes:
ラジオペンチ (1本)
プラスドライバー (1本)
Allen key (4x)

All parts necessary to finish this upgrade are included in the kit. Only exception is that if you are upgrading MMU2 to MMU2S and decided to print the parts on your own.
In case some parts get broken during the assembly, you can reprint them. Please check all plastic parts before starting your build to make sure there are no issues.
The package with all MMU2S STL files is available at prusa3d.com/prusa-i3-printable-parts/
The recommended material is PETG, but you can use also ABS or any material with similar properties to PETG.
For printing individual parts, it is recommended to use Slic3r PE with 0.2 mm layer height, GRID infill at 20%, no supports!

ナットが入らない場合: すべての長さにネジ山のあるネジを使い(通常 M3x10 または M3x18)、反対側からネジを差し込みます。ネジがはめ込まれたら、ナットを回しながら下まではめ込み、その後ネジを外します。
ナットがうまくはまらない:' テープを使ってナットを一時的に固定しすぐにネジを挿入し、その後テープを取り外します。 接着剤の使用は、接着剤が部分的にネジ山に入り込み、ネジを正しく締めることができなくなるため推奨されません。
"ネジ引きテクニック" を使用するように指示する場合、この絵が出てきます。
Treat yourself!
Treat yourself!
Building a 3D printer is a challenge unlike any other and you should treat yourself for every milestone you reach. That is why a bag of Haribo Bears is included!
The biggest issue from the previous builds (MK3, MK2/S) which we had to address was inadequate bear consumption. Many of you didn't have enough bears for all chapters, some even ate them all before they started!
I'm glad to announce that after countless weeks of academic research (hundreds of eaten bears), we came to a solution! Thank us later ;)
Hide the Haribo for now! From our experience an unattended bag with sweets tends to suddenly disappear. We are currently investigating this phenomenon.
Always read all the instructions at current step first, it will help you to understand, what you need to do.
写真だけで組み立てていかないでください! 写真だけでは不十分です。できるだけ短くまとめた説明となっていますので、必ず読みながら進めていきましょう。
他のユーザーからの、コメントを読んでください。 そこには多くの素晴らしいアイディアが載ってあり、私たちもそのフィードバックをもとにマニュアルや組立説明書を改善しています。
最も重要なこと: 組み立てを楽しんでください。お子様、友達、パートナーと一緒に協力してください。 ただし、私たちは争い事には一切責任を負いません;)
