Stop with the Trapezoidal nuts!

Dear Prusa. Please stop using the description ‘trapezoidal’ nuts. You have supplied hexagon and square nuts. A trapezoid is a quadrilateral with only one pair of parallel sides. There is no nut like that. Otherwise the instructions are exceptionally well done but I'm begging now, please stop it, just stop it. It's driving me nuts!

I believe the threads are actually trapezoidal. The nut itself is round.

Right, the Z-axis lead screws are (most likely) trapezoidal, but all the little M3 nuts are not, they are either hexagon or square.

As far as I recall, the only time they refer to the trapezoidal nuts is when they are specifically talking about the nuts that thread onto the lead screws for the Z axis. They refer to the other nuts as M3n, M3nS or M3nN. Not sure what you are going on about.

If you look closely at the assembly description, you'll see that pictures with associated text have been color-coded to avoid misunderstandings.
What I can see is just the round black "nut" and the threaded Z screw called trapezoid.

Understood. Now re-reading the instructions I realize that I made a mistake. Sorry about that 🙄
