Was thinking about you free gift thing as a 3d printer hobbist with a couple of printers . you can personalise these quite easily and very many different version of this Card folding phone stand Print in Place no assembly required https://makerworld.com/en/models/2913245-card-folding-phone-stand-print-in-place-no-assembl?from=search#profileId-3258490 . handy if you want to watch your videos on a mini stand ,cheap and easy kinda sits as a good addition to your previous bottle opener. I’ve got a 3D printer, so making wee personalised items is easy for me. Your apprentice could even pick one up himself and start creating things as a hobby or a small side‑earner. If you ever want anything made, or want help getting started, I can sort you out.
