I have to retain some little LED panels to a flat surface. The 3M doublestick adhesive foam is proving to have less than stellar performance after they warm up for awhile.
I sourced these panels from China and none of the sellers have any clue for bezels. I don't think their translators handled that conversation very well.

Retainer depth of about 3mm. Opening for LEDs: 52-55mm W x 36-36.5mm
Qty needed: 1 dozen. Budget for this project: $10. ;)
Find a pallet with some good looking wood. Put it on your CNC router; cut out a bunch of nice looking and precisely fitted frames. Cost of $0 (aside from time to program the CNC and/or any broken router bits).
An array of high brightness LEDs on an aluminum core board like that usually wants to be heat sunk pretty well to get optimum lifetime. Either the board is screwed to a heatsink with thermal grease in between, or it is attached with thermally conductive double-sided tape like this:

Not sure where to find small quantities of this stuff.
You probably will not find bezels made for these since they are usually put behind diffusers to make uniform panel lights or backlights.
Have you looked a the usual suspects for such, like Mouser or Digi- Key? Even Jameco had them decades back. Probably more like $10@, though. $10 will just about get you a roll of aluminum tape and an Xacto knife...
RTV caulk/adhesive usually handles heat pretty well. There are more expensive high temp versions too. Lay a thick bead along the outside edge and use the original tape to hold it in place till it sets up.
Looks like there is already one hole through it. Can you drill another in the opposite corner and just screw it down?
If no CNC router, time to learn the joys of low-budget 3D printing the old fashioned way. Which is secret code words for less than $10 worth of hot glue - popsicle sticks optional but can be very useful, and hopefully you already have a hot glue gun, because the sub $10 models are not that nice. In low budget, there is no printer other than you manipulating the hot glue gun....
If you want to bolt them on, insert nuts and bolts before applying glue, and capture the nuts.
I've remanufactured quite a few laptop power supply cords using nothing more (after cutting the old plastic down to find the plug, cutting out the shredded section of wire near the plug, and resoldering the wires to the plug.) Sections of popsicle stick provide some non-melty linearity and a bit more strength.
You could also use RTV Silicone, or polyurethane, in the "aka Caulk" form. Just takes longer to harden.
Cut the male and female patterns from ply and stack pieces of Formica and rout them out with a bit with a roller to follow the pattern. Hold the parts with screws and washers clamping them in place. Zing!
