thingiverse

A anti backlash nut adapter for Ender 3 / Other Creality printers. This should fit many other TR8 based printers. Features: No Z height is lost. Orients the anti backlash nut in the correct orientation. Works with round anti backlash nuts, without needing to move extruder motor. Fits with a NEMA17 extruder motor sideways + 5mm (ie fits with a BMG extruder) This part can be printed support free (With decent bridging) It also still fits with 48mm or lifted z motors (Required for my Dual Z System) Assembly: Place m3 nuts into provided internal slots Place anti backlash nut main into position, screw it in with m3 hardware. Insert spring + secondary nut Screw into position on printer (hanging, flat side facing towards printer plate) Thread rod in from the top. This is part of my Ender 3 single stepper dual Z system.
