Caution !!! Hot End Nozzel is still to high. I will be correcting this and updating the stl as I go. I set this part up for 6-32 screws and nuts. I would recommend 1 1/2 inch long for the grip, but 1 can be used just set it with a set of 2 inch. The main body is best with 2 inch. The new main was setup to print and will be tested soon. The fan shroud will have to be offset to fit between the main body and the effector platform. This will be corrected by a new fan shroud.
