TL;DR

What did Uncle Dave (@deebeeeff) use ChatGPT for?

After turning an old Ring doorbell into a button that switches on the Christmas lights and music, a man took photos of it with a ruler and had ChatGPT design a decorative wrap plus a PDF that printed at the exact size. He says the wrap was dimensionally perfect the first time, with the nose sitting right over the button, and his nieces will be thrilled.

What they did

He thought his old Ring doorbell was dead and replaced it, but it still partly worked, so he set it up with Alexa to turn on the indoor Christmas lights and play Christmas music when the button is pushed. Then he photographed the doorbell next to a ruler and had ChatGPT design a wrap for it, along with a PDF set to print at the exact dimensions.

How it went

He says the wrap was dimensionally perfect the first time, with the nose sitting right over the button, and his nieces will be thrilled.

Worth knowing

  • Print at 100% (actual size), not "fit to page," or the measurements will be off. Measure twice, and print a plain-paper test before you use sticker paper.
  • Price check: ChatGPT: free plan; Go: US$8/month (checked Nov 8, 2026).

Here are photos of [object] next to a ruler: [attach]. It measures [width] by [height] and the [button, hole or part] is at [position]. Design a [theme] wrap for it that leaves that part uncovered, then give me a PDF set to print at exact size on [paper size], with a thin cut line and a small scale check box I can measure after printing.
