Overview
When working on my New Astro City, I noticed that the interior could get quite dark; doing maintenance tasks or connecting new game boards was often inconvenienced by the poor visibility. I decided to mount a 24" LED light fixture inside the cabinet, to provide some much-needed extra illumination. This is sort of a "service light" modification to make working in the cabinet easier - it is not a replacement for the marquee lighting fixture. Initially, I held the light fixture in place with zip-ties; however, I wanted something that was sturdier and more aesthetically pleasing. I also wanted anything I used to be non-destructive to the cabinet.
To this end, I designed some custom 3D-printable bracket clips to securely mount the light fixture along the lower edge of the monitor support frame.
You can find a writeup of the whole project, along with 3D print files and the original .blend source file, on my Github page:

I thought this might be useful to some people here, so I thought it'd be worth a share.
Design & Printing
The clips are designed to attach to the lower part of the monitor support frame (the metal structures that are above and below the monitor, and that hold the four corner bolts used to secure it in place). They are made to be printed at 100% fill, and are currently specced for use with a resin printer. They are designed to flex slightly during the installation process, so it may be necessary to adjust the thickness or other print properties if printing them with an FDM printer or with a different material.
The .blend and .stl files have been included in the git repo; feel free to modify them and use them in your own applications.
This print has been validated with the following print settings and postprocessing:
Installation
The lamp chosen for the installation was a Commercial Electric 24" 900 Lumen fixture; it was selected because it was the largest size AC-powered LED fixture I could find at my local hardware store that would fit within the cabinet. Here is a link to the specific model I used. The critical dimensions for use of this clip as-designed are a 40x40mm square tubular section body, and a 20mm radius semicircular bulb extending from one face of the tube section.
A minimum of two clips are necessary for secure installation; I chose to use three for my cabinet.
The bracket clips are designed with a two-stage mounting process, as shown in the diagram above:

This image shows the original temporary mount solution with zip-ties. It should also help contextualize where the fixture is mounted in the cabinet.

This print has been validated with the following print settings and postprocessing:
- Formlabs Form2 printer
- White V4 standard resin
- 0.1mm layer height
- 100% scale
- 20 minute isopropyl alcohol bath
- 60 minute curing time at 60°C, under UV light bulbs
- Lightly sanded to remove support markings

The bracket clips are designed with a two-stage mounting process, as shown in the diagram above:
- Hook the top edge of the clip over the upper edge of the monitor frame, from below. Feed the round portion of the bracket clip around the LED fixture.
- Pull the remaining clip edge inwards, towards the rear of the cabinet, while lifting it up. It should 'click' into place securely around the longer edge of the monitor frame.
