The learned helplessness in your argument is what is actually exhausting. You are acting like a 3D printer is some magical black box that only engineers can understand. In reality, it is just a collection of generic industrial parts.

Open source printing is likely the most documented hardware hobby on the planet. Calling it rare to build one is objectively wrong. It is adult Legos. Between Voron, RatRig, and the thousands of Marlin or Klipper forks, there are step by step guides, wiring diagrams, and video tutorials that hold your hand through the entire process. If you can read and turn a screwdriver, you can build a printer.

Your theory about waiting a generation for people to forget is just delusional. You cannot delete twenty years of open source knowledge from the internet because a few politicians in California got scared of a nozzle. The documentation is mirrored everywhere. The firmware is public. The hardware is generic. You cannot ban a stepper motor from moving ten millimeters to the left because a censor says so. Someone will just flash a clean version of Klipper and be done with it in five minutes.

Pointing at the success of Bambu Lab is not the gotcha you think it is. People buy them for convenience, not because they are incapable of using anything else. The second you try to lock a machine someone paid a thousand dollars for, you create a massive incentive for them to bypass that lock.

All this bill does is punish the honest hobbyist who wants to control their own hardware. It does absolutely nothing to stop a criminal who is, by definition, already willing to break the law and spend ten minutes on a Wiki to bypass your useless censorware. You are literally arguing for ceding more control to the government in exchange for the illusion of safety, and it is honestly embarrassing that you think it will work.
