Here was a request that I completed for NFO Lightbox. Oriented face down with all settings in print profile. Had to up the flow rate to 1.05. If you have any issues with tiny holes, try pushing it up to 1.06 or 1.08 to make sure to get all the tiny corners. Ability to route the light cable through the side hole if mounted on the wall, or if you're going to use the stand, i think it looks a bit better to route it through the bottom of the backplate where i have left a little gap. Hope it works well!

Note: if you want a wall art version of this, all you have to do is cut at the point where the wall is no longer on the side, take off uniform scale, and then scale up the z to around 2 or 3mm. whatever you prefer.
The light strip i use can be found here :
