>I noticed that when using the <a href="https://www.thingiverse.com/thing:3514613">original knob</a> from <a href="https://www.thingiverse.com/s_vayner/designs">s_vayner</a> I kept trying to use my fingertip to spin the knob faster. Adding a fingertip cup made this design perfect for me. I also doubled the length of the threads (so this design may not work with all of the Z-Axis leadscrew support designs out there - but works great with the <a href="https://www.thingiverse.com/thing:3334023">one</a> from <a href="https://www.thingiverse.com/man_from_earth/designs">man from earth</a>). > >I also added the <a href="https://www.thingiverse.com/thing:2752080)">Z-Axis motor mount with shim</a> from <a href="https://www.thingiverse.com/ross_k/designs">Ross K</a> and now both of my Ender 3s travel effortlessly throughout the full range of Z-Axis without binding.
