Unsecured/unstabilized Bowden extruder?

I'm seriously considering changing my Portabee (a Printrbot variant) with a direct-drive extruder, into a Bowden setup.

It looks like the simplest way of doing this is simply to unmount the motor from the X-carriage, leaving only the hot-end on the X-carriage.

The question, then, is if and how to secure the unmounted motor. I saw one Printrbot conversion to a Bowden setup here: [www.thingiverse.com].




As you can see, the drive motor and drive mechanism for the filament appear to be completely unsecured, simply being laid in some location on the table.

Is this an acceptably-stable arrangement for a Bowden setup?

Its fine, the bowden cable is a fixed length so it works.It doesn't care if motor end is secured to anything or not

You could do like is done on the delta printers and attach it to some location on the frame like this on my HE3D printer. That will prevent it shifting around and possibly having the gears catch on something.
