When I first got my Taz 5, I was not able to do anything so delicate as this print, even with the best settings I could find. However, as Cura has continued to improve, my success with mechanisms has slowly improved along with it. I am still having some trouble with shrinkage of internal holes, which is critical to the function of the axles on this model's little truck. This is a 150% scale print, and it still seizes axles about half the time, even with a slight under-extrusion, because the clearance is so small.
This is not on a Mini 2, just a plain original Taz 5 --- Thingiverse forms demand I choose it.
