Prusa Mini Trapezoidal Nut

Hello!

One of my minis (an older one, about 1,000 print hours on it) was binding on Z on lifting, and inspection of the Trapezoidal nut it's pretty worn out. 

 

I searched the eShop for a part, but this looks like the one part they don't stock. I held up the leadscrew to the MK3S, and it appears to be of a higher pitch than those leadscrews. Additionally, a MK3S trap nut won't thread onto a mini lead screw (I had to try).

 

Does anyone out there know the specs on the Mini leadscrew, or where I can source spare parts? I have 36 minis, and this is the first repair I have come across that has left me scratching my head.

Thanks in advance,

-Derek

So support came back, stated the Trap Nut for the mini is not compatible with the MK3S, and is:

 

TR8x4

2mm pitch

I found some on Amazon, Prusa Research is out of stock. How funny a $3.00 part renders a $300 machine useless!
