A car display stand like in the JP Pace museum (https://jp-pace.de/pace.html), mainly created for the 1/18 scale cars from JP Kraemo (https://jp-kraemo.de), also fits the 1/18 scale Boost Wars, but it's close. As the cars are Minichamps 1/18 scale cars it should also fit other models.

For lightning I used a 12v addressable RGB strip and a WLED ESP32 controller, I designed the base so you have an in- and output, so the bases can be connected in series and only one WLED controller need to be used. I used standard 4 pin RGB exentsion connector, e.g. used in PC's to connect to the mainboard. A JST style connector would be better, but I would had to buy some specially for that.

For the top I bought a satin 3mm plexiglass plate, which is 28 cm x 12,50 cm with a corner radius of 1,3 cm, which just slights loose on top.

Last but not least I added white paper to the bottom on the inside, as a reflective layer.

As I have only a Prusa Mini I wasn't able to print the design as one part, therefor I created a dovetail version, which I then glued together, filed all gaps and layer lines, sanded down and painted black.
