Description

Support your AMS HUB or Repair your Broken Feeder!

This part was made to provide a way to lock the clip that holds the A1 Filament AMS Hub onto the Feeder bracket mounted to the Extruder. It uses the factory screw locations to very securely hold it in place. The Factory AMS Hub clip fits inside of this lock. You will put the clip and the AMS Hub together in the proper orientation before mounting it back in place. You will need to use 2 longer screws to hold it in place, I found that two 2.5 mm x 12 mm worked for me. The factory ones are just to short to provide any threads.

This part was developed out of need. We had the unfortunate accident of the AMS Lite unit falling off of the table while connected to the A1 printer. This resulted in the A1 AMS Hub being broken as well as the area on the top of the Feeder bracket that the clip connects onto. The Feeder Bracket is NOT AVAILABLE ONLINE FOR PURCHASE. And getting ahold of Bambu Labs to try to get a replacement part is almost impossible it seems. So This part is a crucial fix to get the A1 working with the AMS Hub. Without it we could not print with the AMS Lite. We could only print from the External Spool.

Is the circled part the part that broke..??

In my situation that part was not broken, but the bottom of the AMS Hub snapped off. When you buy a new Hub it comes with 2 of those clips. The part that broke on mine is the piece that clip actually locks onto ontop of the Feeder Bracket (as Bambu calls it.) here is a picture of the broken area on mine. The 3D printed part holds this clip inside of it. Locking it down and securely holding the AMS Hub to the Feeder Bracket.

For me, yes. I got an A1 Mini with AMS Lite, and it broke/wore out after about a week. that piece is weak, and poorly designed. This part fixed it nicely, though.

Hi there exactly what I needed thanks, only issue is I cannot identify the screws to get larger ones do you know the size? M2 too small M3 too big. do you know the screw size?

The designer has replied

@Creative_3D

The screw I used is a 2.5 mm x 12 mm. Hope that works for you!

Replying to @Creative_3D :

Hmm do you know the pitch of the screws? I do not have M2.5 at the moment but matching the A1 screw to my M2 and M3 screws the M screws seem to have finer threads. See pic attached

Replying to @Creative_3D :

So, the issue I found with using the original screws is that the head doesn't drop fully down the hole as printed. I used a 3/16" drill bit and reamed out the holes, and got the screws to drop further down. The right screw threaded just fine and locked the part down. The left didn't, but maybe I need to go a little further down. I don't have a drill press, and it's hard to be precise with a hand drill. This isn't knocking your part. I'm using an A1 Mini, and the little square piece that holds the hub down wore out about a week after buying the machine. It would print single color fine, but when doing a multi-color print, when it switched filaments, it would dislodge the AMS hub entirely and ruin the print. You part entirely fixed that for me. Kind of fittingly, the failed print was a D&D critical failure art piece that read "Well, shit".

I use an A1 Mini, and AMS Lite. The square bit on top of the hub that holds it down wore out after about a week. When I did multicolor prints, it would pop out when it would change filaments. This fixed it entirely. I was able to use the original screws by reaming out the holes with a 3/16" bit. The right screw grabbed, the left didn't, but maybe I didn't go deep enough. Hard to be precise with a hand drill. Regardless, excellent part. Saved me time and money.

It came out great! User error on this end though since I was unable to install it on my A1 I had a hard time snapping one of the pieces of the AMS attachment back on with this piece sandwiched in-between. Which is probably why the screw holes didn't line up.
