The file 'M12 Installation Tool Head Holder With Locks 3D Printer Model' is (stl) file type, size is 212.6KB.
This is a combination of two other files available on here. I wanted one to mount to the wall but with the 'lock' rings to keep the heads on the holder. There is also a small hole in the center of each post so you can drive a #6 screw through to mount.
