RANDOM ONE... Hiding Ikea Dioder lights

I have these in a display unit…

I’d like something which covers view of the actual light itself, ideally in black or very dark brown.
I have seen one guy listing this…

Sadly I don’t have a 3D printer or any experience getting things printed, I imagine it’s costly. But something similar would be great. There must be something out there that would suffice of can be made to work. I did buyu a piece of acrylic tubing but with my saw I couldn’t cut it, it just gripped the blade.

Anyway I know it’s extremely random and a long shot, but thought I’d give it a shot and see what the minds on here might come up with.
