That definitely sounds like an intensive project

I have some simple buttons and knobs, drawer handles, drawer slides, dryer pest guards that no longer seem to be made, cabinet shelf supports for weird old peg sizes/shapes, plugs for holes to block sharp edges, etc

Your example is going to be really tough in part because the tape itself is fragile. I would absolutely not print things that will touch the magnetic tape itself if you care about the tape.

But the buttons, and possibly even the gears can likely be functionally printed as long as the features arent too small. That’s the biggest issue your example has most likely: minimum feature size
