I needed some light on the A1 since the build plate was sort of dark, I had a set of these lights that I'd bought for a different project and ended up not using (https://www.amazon.com/dp/B09YTXJF5V?ref=ppx_yo2ov_dt_b_product_details&th=1) so I rigged up a bracket for them. The bracket clears the print head when it's at the top of the Z axis. The only thing I don't know is if the lights will interfere with a tall print (I don't think so because they don't look like they hang below the print head, but I haven't tested it yet.

I printed them in PETG with standard profile. I used the screws to mount them instead of the magnetic plates they also come with just because I was worried about the vibration when printing at speed.
