LED-Puck (79mm) Holder or Wall Mount useable for stretcher frame and art (Lithophane)

This is a wall mount for LED pucks with a diameter of 79mm.

PETG or PLA etc. with 0.4mm nozzle and 0.2mm layer height, infill 15%

We wanted to use the wonderful designer Lithophane Moon Lamp by Frank Deschner (https://www.printables.com/de/model/23859-designer-lithophane-moon-lamp/remixes)to produce pictures on stretcher frames for our house and illuminate them with an LED puck (see pictures). 

The mount is designed to be mounted to the wall under a stretcher bar and sits flush on the underside of the fabric. So the light illuminates the moon well, but leaves the rest of the fabric dark.
We'll probably make the background black, with a few little white dots of color to represent stars.
I will add pictures once our little works of art are ready.
At this point, thank you again @Frank Deschner for this super great Litophane model.

Of course, the brackets can also be used as normal wall brackets for staircases, under kitchen cupboards, etc.

Depending on the intended use, I would print the brackets either in PLA (e.g. for stretcher frames) or in PETG (kitchen).

Feel free to upload makes and give the model a like if you like it.
