Comes in two versions, one where the text is readable when you hold it flat in your hand, and one where it's readable when looking at it from above on the machine.Just unscrew any of the screws that hold the printer together, put it through the mount and screw it back in. The nozzle mag snaps onto the mount.The holes are threaded so you need to print this with a layer height of 0.1mm at most, preferably slow as well to get nice clean edges on everything. I used 0.08mm and 35mm/s.Also, let the print cool down before pulling if off. It's very easy to bend the mount when it's still warm which will make it grip poorly.
