A printer is an interesting example, because for many people a 3d printer is just a means to an end, there is a big difference between hot rodding a used $70 ender in order to print 10 minute benches, and buying a prusa or bambu in order to manufacture parts for their business.
These two sides get conflated a lot, with conversations leaning between them and people missing the other sides point, there is a sliding scale with a lot of hobbies with this I think.

Why do you keep animals shackled in your home, perform surgeries on them, remove their agency.
Having a pet at all is antithetical to vegan ideology, and making a decision about their diet (without their consent, because animals can’t consent) is exactly what you are attacking others for.
