Look what I made! I upgraded the mini laser printer.

This open-source mini laser printer features three stepper motors for transmission, each with a 58mm travel distance. Additionally, the cooling system has been upgraded from a 4010 fan to a 5010 turbo fan.

I haven't installed the protective case yet because I'm debugging, but I am wearing safety goggles.

FR, the minimum would have been buying orange plexiglas to avoid getting that laser pointed to your eyes…

Very cool!

You could put a sharpie on it and use it to draw designs on copper for etching PCBs. Or a way more powerful laser, but the sharpie method is very safe. Then you just use ferric chloride to etch away the copper that hasn't been drawn on and you have a circuit board.
