could you make a video about how to build this?

I likely will never have the time to do that, but thanks for the suggestion.

your idea is wonderful, see also this rgb design lamp:

I've made an update to the design. There is now a fixed "eye-guard" that should be affixed to the base, and a rotating "turn wheel" that sits on top of it and can be turned. This two component design fixes light leakage that may cause light to shine directly into the user's eyes. The modified parts require a new base with a groove for the eye-guard.

If you already printed your base and cover, you can retrofit your existing setup by printing "EyeGuard-ForOldStyleBase" and cutting out the dividers from your old cover piece so it fits around the eye guard

Awesome. Just what you need to teach additive and subtractive colors in physics class.

Good point! I'll add "physics" and "education" to the keywords :)
