The two upright posts that hold the mount for the Nimble extruder and Precision Piezo20 are extremely fragile - just trying to safely put a thread in them snapped one and then trying to set up a fixture to hold the piece in place for gluing popped the top off the other one. May I suggest a thicker wall with a hole on top. Or skip the plastic stud and just do holes where metal spacers, bolts and washers could perform the same function (just thinking ahead to the first time I have to fight with a stuck filament or I need to remove the drive cable to the Nimble which will likely also crack these plastic studs). Love the idea of it all being printed but ABS and PLA have the same problem as any torque breaks at the layer boundaries which is the weakest direction. If the mount formed a box around the Piezo20, with one side open for the circuit board (and for inserting the Piezo20) and part of the opposite wall open to lock the E3D in with the wedge, it could be screw mounted down through the Nimble mount and top of the box, eliminating most of the torque issues.
