<p>I read something the other day about a guy who found a way to knock over completed prints with the printer head itself, then slide them to the edge of the build plate, where they fall into a box/basket. This allows printing several Eiffel Towers while you sleep for example. It doesn't work with skirts (duh), and the adhesion has to be just right not to wake up with a pile of spaghetti, but it still sounds useful.</p>

<p>Well, now I cannot re-find the description I read; does anyone know what this process is called? Is there an easy way I can perform such an end-of-print action on my CR-10 with a cura plugin? If such a thing takes a touch of end-time custom gcode, is there a proof of concept rough draft or demo I can start tinkering with? Any more info is helpful.</p>
