Edit: Hmm.. It seems the honeycomb version is coming on the Mini+ now and it is injection molded? Oh well.
To make it printable, I couldn't offset the lettering and had to make it go all the way to the bed. Also, I took note of where there was extra material around the screw holes so the screw wouldn't plow through the material when you tightened everything down.
There is ~1mm honeycomb depth difference where the rails are supported by the plate since I really didn't want to screw with the integrity of the frame and the plates actual function, so that might look weird.
