Now here is a silly little thing.
We figured out that at the max Z sometimes the drive cable can get hung up on the screw holder.

The simplest way to fix it is to move the extruder out a bit. Initially, I had the extruder hanging by one screw, but didn't like that.
So here is the newfangled fantastic solution. (yeah a bit over the top I know)

A simple little extender to move the stepper out of the way.

The STL models are checked and optimised. The parts that need a different orientation to print properly are rotated to the preferred printing position.

The Nimble Extruder

With an installed weight of less than 27 grams on your carriage/effector the Zesty Nimble is the smallest and lightest extruder you can buy, it has ample torque and can be mounted in multiple orientations.

The Nimble is available from Zesty Technology.
