Hi, I bought this printer about a month ago, having an issue with the Z-axis (it seems that Trapezoidal Screw is not exactly alligned) I'd like to buy two spare Ztop mount (No.A8) to perform some tests

Could you let me know where I can buy these spare parts?

Thanks a lot
Ciao

Thanks,
actually, I am also thinking about it, but could not print yet, I was hoping to do it sooner ....
I've found a 3d models modified to use a ball bearing, however I'm going to replace the Trapezoidal Screw before.

Thanks a lot
