About this 3D model

Knob to move the Z axis manuallyThere are two pieces, the knob and the piece used to replace the acrylic one on the printer, (it will hold the Z axis straight). Double extrusion file (also single)!!!! I printed it for a Geeetech A20M and a Ender 3.Obviously it works well on other printers with single Z-axis, if you print it and mount it on your printer, please let me know with a comment or a photo.
