This provides a slot suitable for items with clips, such as knives, razors, measuring tape, etc... Simple but sturdy design it should handle things sliding in and out of the channel pretty well. It is compatible with the universal clips in the set:

The clips might require minor sanding for an easier fit as this is designed to be pretty tight.

The light channel has been lengthened to 335mm and widened to accommodate this 12 volt LED strip:

I have many spare transformers lying around, so I wired it directly to a transformer and plugged it into an IOT switched outlet. I can turn it on and off from my phone.

Long Light Channel for makebreakrepeat's CR-10 Light fixture

Having put together a Zoom studio, I found that the Neewer LED lights I was using to be a bit harsh on my eyes. I didn't need the full output of the lights, as I just used them for fill lights. 

I always wanted a diffuser or softbox, but didn't see any that I liked at a price point that suited me. I finally got around to designing this and it seems to work fine. 

It is designed a little on the loose side for a drop-over-the-top implementation rather than snap or pressure fit. There's enough room for you to scale to your liking. There's also enough room in the channel to use nano tape so this should fit a number of different brands of lights if they are similar in profile.

This is the light I use (non-monetized link) for your reference:
