Just a simple little bar I designed to go inside the Z-axis bar of the Ender 3/Pro. Bring it into your favorite modeling software and attach anything to it to hang from your Creality printer's Z-Axis bar! I originally attached some 3D-printed letters but anything will work with it. Recommend 100% infill, doesn't take long and needs no supports.
Use your Slicer settings to adjust it to any length you want. The one I have included here goes most of the way across the Z-axis of the Ender 3 Pro.
