I like to keep the 3D printed look for spare parts, because its a good conversation starter and it often blows peoples minds if you tell them how cheap it was to produce. I was able to get at least 6 people into 3D printing now that way.
If people have little kids, or dogs that like to “counter surf,” guards are a pretty much a must (we just took the knobs completely off when our kids were little), acquaintances of ours lost their home to fire when the dog counter surfed and turned the gas stove on. I don’t remember what caught everything on fire that was on the stove, but they lost everything, and it killed the pets too.
