For the concert lighting engineer in your life, here's an audience blinder fixture that you can attach to a keychain.
Print face-down with supports, preferrably in PETG. The bracket part is sturdy but flexible in PETG; your mileage may vary with PLA or other materials.
As always the original design file (fusion360) is included, so feel free to improve it (or learn from it)!
