AMS Hub Reinforcement 7 & Cable Organizer

👋 Hi Maker!
Thanks for taking a look at my model!
If you like my work, leave a LIKE and hit FOLLOW — it only takes a second for you, but it’s a huge motivation for me to keep designing and sharing new models.

📦 Model Description

This accessory is made up of three main components:

• Bambu Lab AMS hub reinforcement, precisely calibrated to fit perfectly
• Modular cable chain
• Power cable guide, included in version 7

👉 It’s also possible to use only the filament guides with the hotend power cable housing, if preferred.
Since I recently repositioned the AMS, I personally found this solution to be more practical and versatile.

🧱 Main Features

• Stabilizes the hub vertically, preventing flexing
  → hub flex can cause filament loading issues
• Guides the filament into the hub while keeping it perfectly perpendicular
  👉 Trust me, there’s nothing more frustrating than trying to figure out why the filament won’t load after every print—especially when it works perfectly on the original stand.
• Keeps the AMS Lite Bowden tubes and the hotend power cable organized, preventing tangling
• Maintains vertical alignment of the Bowden tubes, improving reliability and consistency during filament changes

✅ Thanks to this simple modification, loading errors are virtually eliminated.

🔧 Improvements

• The hub is now much easier to remove
• Bowden tube insertion is easier, thanks to the removable top section
• If the AMS is not positioned on the right side of the printer, cable guides with integrated hotend power cable routing could be inconvenient
  👉 Using a separate cable guide makes the setup more comfortable and flexible

📌 Included Segments

• Standard cable guides
• Cable guides with hotend power cable housing
• Spring-loaded guides, to be mounted above the toolhead to preserve the hub’s spring action
• Guides with external spool inlet

🔄 All of this is achieved without interfering with the hub’s original spring-loaded movement — full functionality is preserved.

🖨️ Printing Tips

• No special settings required.
• Since this accessory fits onto the hub, different materials may behave slightly differently regarding tolerances and shrinkage.
• Supports are enabled purely for aesthetics, but are not strictly necessary.
• I recommend using black filament if you print the hotend cable guide, as it blends in perfectly.
• ✔️ PLA or PETG are sufficient — no need for expensive filaments.
