That is the spirit! A friend recommended me to buy a Bambu P2S: there are parts I want to print and I don't want to model then send them to have them printed, nor to bother my friend all the time. Funnily enough I've got magnets falling too: for an alarm system on the doors/windows and they don't hold well anymore after the years. Then my car's radar detection device (fully legal) doesn't fit nicely in the phone holder I use to that effect: I want it a specific angle (I want it both inclined and facing towards me a bit). So I'll model those and just print them. There are a few things like that where I keep thinking: "If I had a 3D printer, I'd just print a part".

Most importantly: I've got a 11 y/o and I think it's cool for the kid to see how it works.

Already watch a few vids. Doesn't look too hard for simple things.
