Summary Do you have one Old PowerWASP model and your extruder head is gone? You need a new original WASP Jhead, but first you need to print this holder to mount the new unified Delta WASP extruder on your machine. This holder is vertically adjustable to make your home Z high. You have TWO versions, depending if you use a high or a low stiffness bed. Print it 100% with ASA or a very good ABS to have a stiff and solid object. All the best from Italy! :) NOTE: November 29 - We uploaded a new reinforced holder! :) Print Settings Notes: Print 100% in ABS or ASA - No support required
