From what I have been informed, this will not fit the A1 mini. Only the A1. I introduce you to the Bambu camera relocator for A1 printer. I did not care for the location of the A1 camera. I felt like it doesn't show first layer very well. So I designed a mount to move it up. The body just snaps in place over the housing. There are 3 holes so you can choose if you want it higher or lower.

This requires 1 M3x8mm screw.

I have 2 camera holders. One is labeled heatset. The hole diameter is make for you to press in a heatset insert so you can easily move it from hole to hole! The one labeled screw is a smaller hole. This one still uses an M3x8mm screw. Screw the M3 into the holder and it will make the threads. I did it this way in case you don't have access to inserts.

There are 2 pictures with the printer at home position. One picture is the stock camera location. The other picture is in the new location.

Install procedure.

1. Look at the bambu wiki to remove the A1 camera. It is fairly simple.
2. Print parts. I included a print profile to show orientation that I printed them in. 
3. Pop the Bambu A1 cover plate off. It is not that hard but be careful as the upper left corner has a long tab. Best to pop it off as straight as possible.
4. Use screw and screw both parts together.
5. Take the camera cord and fish it through the rectangle and through the round part of the a1 camera holder.
6. Connect camera back up to power cord.
7. Push camera into the holder. It has tabs and has a very small click in. The face of the camera should be flush with the holder.
8. Power on and look at angle.
   1. If you don't like the angle, pop camera back out, disconnect power. Pop body off and move to desired hole.
      1. Careful not to damage camera power cord moving it.
   2. Repeat previous steps to install camera
9. Once you are happy with the angle, slide cap over the back of the camera holder.
10. All done!

I hope you enjoy it!
