Lol maybe! Either way, convince your friends and family and it will spread!

Feel ya there!

I have had good conversations about fastener heads (screw driver bits) and getting rid of timezones recently, my people

You know! ❤️

Torx for anything that needs to be torqued or used with power tools, Robertson (square) for anything intended to be used with hand tools or more finer work (a screwdriver)

Right, field maintenance, especially when you don't have access to tools is a bit of an exception. Personally I think using take down pins for guns is the way to go for field maintenance anyway.

Lol absolutely, stripped screws are the worst

Lol I think it would just be 3 am or 9pm depending on which way you are talking

Ya Ikea standardized on hex because it's cheap to mass produce. It definitely strips though.

Torx has slowly been gaining popularity in the US for a decade or two now, but sadly Phillips is still pretty popular and hex is pretty common also, you will see the square/Robertson screws a lot in electrical panels and in cabinetry but not super common at the hardware store.

The way I see it, anything with a square bit can be done by with a hand held screw driver, and anything with a torx bit should probably be torqued to a certain amount and/or be used with a screw gun. Square/Robertson bits are used super often in things like electrical panels and electronics. They are becoming pretty common for cabinetry also. I doubt you'll see a torx screw in cabinets.

**Get a Bambu printer. Do not get an ender. **

I own quite a few 3d printers and got into it in the late 2000s with MakerBot. I have learned a lot, and have tried to drag friends into the hobby, and most of them have been highly frustrated until Bambu came along.

Please, just get a Bambu printer, right now nothing else compares. Bambu isn't fully FOSS (firmware isn't) but people are working on open source firmware. Their slicer software is open source.

For printing anything for a car, don't use PLA, I'd suggest PETG, ABS, ASA, or Nylon if you get a printer that can handle that (prob more than $300). PLA will warp in a car from heat/sunlight.

A Bambu A1 is $340 without the AMS lite. If you get that and like it, I'd recommend getting the AMS lite so you can do multi color and multi material prints. It can handle PLA and PETG which should meet most hobby needs. If you want to get into actually doing robotics stuff with it more seriously, sell the A1 and get a P1P.

Square (Robertson) and/or torx depending on application. Square should be for everyday things and torx should be for anything mechanical, yes I know there is a big gray area in the middle there, but flat head, phillips, and hex need to go.
