Why TX 8 ?!?!?
I finally have a bazzilion drives and wrenches for the nearly ubiqitious M3 bolts, and th eXL uses a freakin' TX8 drive to change the hot end assembly??? WTFudge? Why. At least throw a handful of them in the kit so that a year later I have a fighting chance of finding it. For some reason, I keep fidning the TX6 over and over and even though I know it's too small, I keep on trying it. The MK4 uses big finger tightened knobs, but on the other printer, lets use a totally obscure thing. And it's not like you can use a bit to get it, you have to have a wrench to reach in.

Having built my aircraft over the course of a decade I have way more than a bazzilion drives and wrenches. Once I purchased my XL I also brought a nozzle wrench from Amazon. A bazzilion and one wrenches are always nice to have.

Can't tell you why Prusa is now moving more and more toward Torx but it's not just the XL for sure. There's a Tx8 wrench in the XL tool bag, and I have probably a handful more from other Prusa printers. I use my little XL tool caddy https://www.printables.com/model/473686 to keep all the tools readily available.

Interestingly, most Torx sets seem to start at 9, not 8. I had to get the 'mini' set at Homedepot. The standard sets look like they have one small enough, I was surprised.
I know I got a T8 with the XL, but I'm always misplacing things. Like I said, I have the drive for the M3 bolts all over my work area.

Thank you for a good overview article. Still, it remains unclear WHY we now have an unholy mess of Torx and hex.

And to kill some time. The History Guy covers the history of Phillips screw drivers and why Canada has a different kind.

Sometimes a hex screw can get old and the hex key can not get grip anymore. Torx does not have this problem, at least it did not happen to me jet.
With the prusa printers many people build their own printer and not all people are evenly handy with tools. Some people might misuse tools or put too much force on screws resulting in a damaged head. If that damaged head is inside the extruder it might be a big hassle to get it out again.
Also torx just kind of sticks to the head of the screwdriver, you do not need to hold it or have a magnetic head. If I could I would use torx everywhere. But I cant so I also have a gazilion tools.
