Description

1/26/2026 update: u/Flyrockets informed me of an error that is occurring on Firmware 01.01.50.24 (beta tester firmware) that the nozzle will hit the build plate aligner after the third layer and cause an error, causing the print to stop. I have updated this design to lower the aligner to be 0.5mm above the Textured PEI build plate vs the 3mm it was previously. This shouldn't cause any errors as the third layer should be over 0.5mm in most cases, but I do not have the 01.01.50.24 firmware to confirm. Please let me know if you experience any errors while using this updated design and I will update it again. To easily remove your build plate aligner and update to the new one, remove the old build plate aligner starting with the lober side and simply push it down and off the heat bed.

If you are enrolled in the beta firmware program with Bambu, please check your printer firmware before printing. If you are enrolled in the beta firmware program with Bambu, you will need the updated design. If you are not part of the beta firmware program, the original design will work great for you if your firmware is 01.01.01.00 (stock firmware)

This is a guide for aligning the build plate on the Bambu Lab A1 printer I designed in Fusion 360. I have been having problems getting my build plate perfectly straight on my new A1 printer so I designed this to clip on to the right rear corner of the A1 heatbed to help align the build plate. This build plate aligner prints in less than 20 minutes and uses less than five grams of filament. This design has been tested to ensure it does not interfere with bed leveling or nozzle cleaning. This design needs to be printed in the orientation I have uploaded it in for proper fit.

You can not mirror this design and use it on the left rear side of the bed. The nozzle will hit it when changing filaments or cleaning the nozzle and cause the print to stop.

Printing in PLA works, but PETG is the better material to use for this aligner. If you find this model to be a little loose, it is to ensure it can be removed from your bed if you do not want it on anymore. I had numerous versions of this that fit perfectly but had to be cut off to be removed. I do not want you to have to cut this off of your printer if you want it removed.

@Flyrockets

WARNING the latest beta firmware 01.01.50.24 will cause a collision with this when it checks for “filament wrapped detection” it actually moves the nozzle outside the print bed to where this is installed! bummer because I really like this aligner!

(Edited)

@Norder

Just realized this was the reason for my constant errors after the second layer. This is an important comment.

@user_2097678733

Replying to @Norder :

so you turn it off?

@Norder

Replying to @user_2097678733 :

I removed the print. Prioritized the detection.

Solid print, but the edges aren’t tall enough on my A1 to actually help align the plate. it sits basically flush with the bottom of the plate..

@DasDragon

I have the same problem with mine, do you think there may have been a bed adjustment with the wire change due to the recall?

@iEVLegacy

Replying to @DasDragon :

that is a valid point, however, I’m simply not sure!

@DasDragon

yah me neither I only got 1 lol. but mine has the new power cord on the bed. I got a hunch there’s a difference. your print seems to fit too ways. as planned, or just flush with the top of the bed and it shows there should be more overlap. all good. stil works just not really as effective as it could be

@IONX35

I printed it out for the left and right and both fit well. The nozzle has no problems with it and the print plate is easy to place. Many thanks for providing the 3D model.

@nasirloo

Nice, could you share your design?

@IONX35

Replying to @nasirloo :

I hope this information helps you. It is not my design. I have actually mirrored the "A1 bed guide V11 fileted.stl" in Bambu Studio.

@zh4sh9yqv4

Replying to @nasirloo :

simply mirror the original

had a problem with it catching the head and would cause a error and stop printing A1

@shiruvan

same

@AdriLab3D

Did you resolve it?

@superduperc2020

same i had to remove mine but it is a good idea.

printed very well!! but have no clue how to put it on.

@Obecny75

did you ever figure it out? I tried to put mine on and it won't fit

@jhermann

Replying to @Obecny75 :

Take the long edge and slide it in tilted to the bed until it hits the top edge of teh bed. Make sure the short end is aligned with the back of teh bed, then slide the guard into position (turn clockwise, always keeeping that long ridge on the bed'S edge). Or put another way: let the right edge of the bed catch the ridge, then turn clockwise until the back ridge snaps in (press bottom of guard upwards).

@TheXak

Replying to @jhermann :

it looks like it's bending the plastic frame around my heatbed. is that supposed to happen?

@lifesoccult

I have a new A1 purchased over Black Friday 2024, and this doesn't fit. It seems that the print is supposed to press into a screw hole on the bottom side of the bed? Well either that hole is shallower now or something else changed because I can't press fit this into place. It just falls off/doesn't click.

@mdede439

This also happened to me. I suppose this print doesn't work anymore.

printed quick and easy. but for me it's not quite helping to align the sheet

@TheXak

I can't get mine to fit on my A1. not really sure what happened because i didn't change any print settings.

The lip fo alignment is so low it is not worth printing. Made no difference at all

Very good design, unfortunately my build plate is higher than the frame itself, so I hit it when attaching it and it's not centered
