Hydra - Enhanced Bambu Lab AMS

Notice!

This is only compatible with the original AMS. Please view my other designs for designs supporting other AMS systems, there are plenty.

Update August 5, 2026

Hydra has been updated to version 1.13. Changes:

- Improved split design, no screws used for assembly.

- Support for (upcoming) cover set, suitable for top mounted heaters such as the Sunlu AMS heater.

- The upcoming cover set includes covers for the feeders, PTFE tubes and motor, shielding the electronics from direct heating.

- Support boxes integrated in the design so they can't accidentally be moved and merge with the main pieces. The support boxes are set to just 5% infill and 1 wall for the print profiles.

- There is also a version completely without support boxes, you can use this if you want to use your own custom supports.

Please use the print profiles if you can, they're tried and tested with correct print settings and supports.

Update May 7, 2026

Hydra has been updated to version 1.12. Changes:

- RFID performance greatly improved, holders tilted back and up which aligns better with the spool tags for a more reliable reading.

- RFID board sockets and hex cutouts completely redesigned.

- Aligned the two rear screw holes, they were previously a tiny bit off.

- AMS main board mounting improved.

When using spools with RFID tags, it's recommended to use the optional spool guides.

Please use the print profiles if you can, they're tried and tested with correct print settings and supports.

Update March 9, 2026

Hydra has been updated to version 1.11. Changes:

- 1.5 mm narrower total width , making it easier to fit in the AMS box without squeezing it in.

- Front rollers slightly larger cutout for the bearings.

- Middle/rear dovetail removed as it made assembly difficult and it was not really needed anyway, the motor mounts hold it steady in the rear.

- New front dovetail to align the front lip.

- Small adjustment to the AMS main board mount.

- RFID friction fit mount optimized.

Please use the print profiles if you can, they're tried and tested with correct print settings and supports.

Update February 1, 2026

Hydra for the original AMS has been updated to version 1.10, it's the first update of the series for a very long time and as it's largely based off the newer Hydra for the AMS 2 PRO so it comes with some nice improvements, especially support for even wider spools and PTFE tubes replaceable from the top.

Changes:

- Rebranding, Hydra AMS is now known as Hydra - Enhanced Bambu Lab AMS to avoid confusion and for which AMS system this is for.

- Feeders tilted back to clear very full spools (avoids very full spools hitting the feeder or load button).

- New: PTFE tubes replaceable from top.

- New: Removable and reversible front and rear spool guides.

- Improved rear roller positions, allowing for slightly larger diameter spools.

- Optimized Hydra tray position and placement of the front locking tabs.

- You must use some manual supports, see instructions below. If you're uncertain, please use the print profiles where all of this is prepared.

- New built-in support boxes, these prevent the side walls of the main print from warping. Previously, the supports were just low infill waste prints but these new boxes are very much usable (and stackable!), there will be containers and add-ons for these soon, see the pic below, the orange boxes. You must still use some manual supports, see instructions below. If you're uncertain, please use the print profiles where all of this is prepared.
