Is 3D printing worth it?

A few real-world workshop examples that make use of 3D-printing.
I hate how 3D printers are always advertised with the things they can make. Mostly figures or models of stuff that just looks cool in the first moment, but very few people actually need that.
That's why I didn't want to dive into 3D printing for some time. Since I then had access to the printer of my dad I came up with a few things that actually make good use of a printer for the workshop.
The materials I used were PLA and PETG. Everything that was white was PETG and the rest was PLA.
I use soldiworks for designing.
