I added some Multiboard tiles to the backsplash/wall of my work area. I needed more light, so I created this in Fusion 360. It is parametric, and initially exported to be 8 tiles wide. I used two 8mm LED strips, 12v in my case, from Amazon. There is a slot in the end pieces for wires to pass through and through holes for zip ties, for cable management.

Parameters that can be adjusted are how many tiles wide they are, and the size and number of LED strips.

Printing for the mounts: orient so the top is on the print bed. I printed with standard Multiboard settings. it's a pretty easy print IMO.

Printing for the diffusers: I used some info from this guide to print some clear PETG https://www.printables.com/model/15310-how-to-print-glass. It turned out fine for my needs.

Things to improve: t's a bit plain in appearance, I might try to add some more chamfer or fillets. to make it less boring. The push fit is pretty tight for me, so I don't think it needs the new bolt lock pattern that Keep Making just announced, but I could add that pretty easily I think. There are gaps between the pieces that let light leak through. I need to design something that can just clip on and spruce it up a bit. I plan to create or remix a mount for some Wago lever lock terminals, to help with cable management.
