The AMS Mini offers a minimum way to manage & protect multiple filaments for your A1 printer while maintaining the stock design of the AMS Lite. (Please note that the RFID functionality will not be active in this design, so keep this in mind if it's an important feature for you!)

1. Component Set

AMS Mini Chamber (Rotatable for enhanced accessibility)
Top Mount Bracket
Reversed Numbers Cap
Feeder Guard & PTFE Tube connectors (supporting TPU, WIP)
PTFE Tube connectors for PolyDryer users (WIP)

2. Print Intro

Flow Rate Calibration: Required
Printer Used: A1 Combo
Nozzle Size: 0.4 mm
Bed Type: Smooth High-Temperature Plate for optimal surface quality
Layer Height & Print Profile: 0.16 mm High Quality
Support: Customized for easy removal (tested with PLA & PETG)
Total Print Time: Around 12 hours
Total Filament Cost: Around 250 g

3. Filament Suggestions

For the best results, I recommend the following Bambu Lab PLA colors:
Bambu Lab PLA light gray - (for AMS mini Chamber)
Bambu Lab PLA gray - (forTop Mount Bracket)
Bambu Lab PLA Blue gray - (forReversed Numbers Cap - cap)
Bambu Lab PLA White - (forReversed Numbers Cap - number)
Using these four colors will help you achieve the original AMS Lite look, but feel free to customize in Bambu Studio!
While PETG can provide a stronger build, PLA has worked well in my experience.

4. Non-3D Printed Parts

Scissors or pliers (for support material removal)
Screwdriver
5 pcs x M3x20 screws (exact diameter included)
3 pcs x M2x6 screws (exact diameter included)
2 pcs x BT2x5 B0017 screws (available from the AMS Lite)
4 x PTFE tubes (optional)

4. ***Assemble guide***

Step 1: Disassemble the main body of your AMS Lite. For guidance, check this Bambu Lab Wiki article.
Step 2: Place the AMS motherboard inside the chamber and secure it with screws.
Step 3: Install the AMS Mini Chamber onto the Top Mount Bracket and secure it with screws.
Step 4: Install the Left/Right Feeder Units.
Step 5: Install the Reversed Number Caps.
Done! Enjoy your new setup!

5. Why I made this (In case you are interested…)

The original AMS Lite offering no protection for filaments.
The bulkiness and inefficiency of the Bambu Lab top mount solution, which provided no filament protection and resulted in unexpected spool drops (I experienced three!).
While the DrySphere 4D is an excellent all-in-one solution, it's quite time-consuming to assemble.
Many other third-party solutions look unappealing, and I wanted to maintain the aesthetic of the original AMS Lite.

Excellent design. Wanted to print it with your suggested colors but unfortunately we don’t have resellers of Bambu filaments in my country and shipping would be expensive. Still looks great tho. I used the remix version for the chamber as it has more space for cables and the number orientation. Also hoped that you have assembly instructions. Thanks for the model! I made a video for it. https://www.instagram.com/reel/DBoRuqyT2x7/?igsh=MWVkbWlzOGhwanRwaw==

Hello. Thank you very much, I am a beginner and I have printed it and it is superbly done. You detailed all the steps perfectly. Regarding the screws, are all the screws included in the toolbox or with the AMS? I just want to be sure before I start disassembling everything. Thank you Chantal from Quebec!

Replying to @chanchan :

- 3pcs BT2*5 (B0017) from ams lite mainboard, - 4pcs BT2*5 (B0017)from ams litefeeder units - 5pcs M3*20 screws: 2 for securing the Top Mount Bracket, 3 for securing the chamber. M3*16 also fits.

A heartfelt thank you, I am incredibly happy with the support of my AMS. I'm boosting you to encourage you to continue your excellent work. Here is my assembly chanchan!

I am surprised you did not mount the ams min right to the S4. 4 new holes up the middle and you can eliminate so much tubing. Even put the spool sensors back in.

@tbevivino

Replying to @NachoRolling :

Can you explain what you mean by this? I am interested in this idea but am not sure what you mean. Thanks!

Hello this bricked my AMS lite. I can feel heat on the 16V DCA marked transductor, but my A1 does not detect the ams lite. Any help please? Thanks

The designer has replied

@user_4290665555

hello this is new to me no one have ever reported similar issues so far. are you sure all of the wires were connected?

@muffin87

Replying to @user_4290665555 :

It seems they are all connected fine. But I'm gonna show it to you. It was working fine before. Any idea what I could be missing?

@user_4290665555

Replying to @muffin87 :

Hey, I’m really sorry to hear this. The only thing I found online is some debugging instructions on the wiki. You might want to take a look at the A1 connectors on the base of the machine. I don’t have a lot of expertise in electronics, so I’d recommend reaching out to the Bambu Lab team for further support.

Bambu PETG for the board enclosure?

Came out great. I love the design. Swapped the motor wires and the numerical order still works left to right. I also printed some PTFE adapters for the motor inlets, installed some PTFE adapters, and attached to a couple of the Sovol dryers.

@gibi310

do you have any problems when the filament retracts to change the color being used?

@mk42workshop

Boosted

Replying to @gibi310 :

I haven't had any troubles with retracts. The AMS Lite doesn't really retract much. It would be better to have the clutches, but I wouldn't say they're necessary. I did have problems with the Sovol dryers and feeding. The places to put in the PTFE tubing were angled HORRIBLY. So the AMS Lite motors couldn't pull nor retract reliably. There are angled pieces that can be printed to have a better angle. Ultimately I went with Polydryer boxes and haven't had an issue since.

Replying to @mk42workshop :

That's great to hear! I have some Creality Space Pi Plus boxes that I want to try this with. Hopefully the angle isn't too bad.

nice print. wish there were a secret or something better to secure the rear of the mini housing without having to glue it together. would of added more pics of installation but was limited to 8

@user_2777791125

The rear can be closed with a screw. There is a screwhole you can open

Replying to @user_2777791125 :

ok thank you

@Eathon_Tao

Why the left/right feeder units reverse? Could you provide a noraml one , like 1-2-3-4 in the picture. And the original feeder units fixed with 4 screws, but only two in yours.

The designer has replied

@user_4290665555

1. I think it looks more balanced visually in this way you may try to install it in the original sequence. 2. 2 is enough in my case and I simply wanted to keep the use of non printed part as few as possible lol sorry if this is something feels uncomfortable with

@Eathon_Tao

Replying to @user_4290665555 :

I'm sorry, following the original sequence won't work， because the interfaces of the feeder units are incompatible, and they will also interfere with the Top Mount Bracket.

Just swap the red and blue ribbon on the motherboard and it'll be correct. Look at my review.

I love this design; everything fits perfectly <3. However, I think it needs a bit of improvement: - Only one screw to connect the feeder is not strong enough. - The body and the AMS feeder are too close together, so I can't use the feeder cap from other designs. And finally, thank you for such a wonderful design <3.

@user_4290665555

hey thank you so much for the feedback! for point 3 would you mind share a sample print that is not compatible with this print? I will take a look into this

where do I find the desin for that cable protector you are using there? like a cable chain looking thing

Really good print. It's not as clear for installing, because you have to disassemble your AMS lite. It's not straight forward, so you'll have to look at videos from Bambu and find screws. But once you get it printed. You'll figure it out. It's not hard, just cumbersome. But once you are done. It looks so good. I use Polymaker's boxes, so this is perfect as they all sit behind the printer and never comes out of their dry boxes.
